1.) Do you have any advice on any of this?
i would say definitely try to make a team because you will enjoy it so much and i think that the problems that you are anticipating with the upperclassmen are probably not going to happen. if girls really want to be on the team, they wont care. plus, i doubt you and your friend would be the ones making all the corrections. generally the coaches make most of the corrections. girls on the team do correct each other, but the upperclassmen will probably correct you as much as you correct them by the end of the season, because everyone messes up at some point. i wouldnt worry about it.
2.) Do you have any ideas on how to get the upper classmen to go along with it?
see above, and i see no reason why they wouldn't if they really love dancing. the most important thing on a team isnt how amazing the dancers' techniques are (although that helps) as much as how passionate they are about it. i would start to try to find girls who already love dance, maybe find girls from local studios, or girls that used to studio dance
and now some general questions
1.) How many people are on a normal dance team?
i have seen between 5 and 40 but most teams are somewhere between 15 and 25. but only take as many girls as deserve to be on it, because i have seen an AMAZING team with only 8 girls, and it looks better to be a smaller, better team than bigger and sloppier
2.) What are some good fundraising ideas?
carwashes are great

but our team had a lot of success with individual sales such as cookie dough, candy, chocalate bars, christmas items, etc. also, having a recital with more interesting pieces (like hip-hop or jazz) for about 5 dollars makes a lot of money.
3.) How much money does a team need to start out with(competing and non-competing)? it depends on each team. so far, our team has spent about 350 per girl on uniforms, shoes, competition entrance fees, etc. camp will cost another 300 or so. and lodging, etc. for comps. will cost hundreds, depending on how well we do this year
4.) How should we advertise?
lots of signs and posters, at studios, over your school announcements, and have open gyms the few weeks beforehand for interested girls to kind of see what it would be like and practice skills etc.
5.) Does anyone have a scoring sheet for auditions(tryouts) whatever you want to call them?
this is the link to my old junior high team tryout score sheet
students.uwsp.edu . . .
obviously for a high school tryout you would make it more difficult, make the harder skills non-optional, and add more challenging skills like triples and quads, switch to second leaps, a hard kick set (maybe fan kicks and illusions?) etc. oh and the quick learn on the sheet is where about 15 minutes before the actual audition girls trying out are tought a few simple eight counts they haven't learned before and have 10 minutes or so to practice before the tryout. it is to see how fast you learn, but not really necessary for a tryout.
6.) Do you have any ideas on what we could say to the principle, should we bring the coach with us?
yes, bring the coach with you, and just emphasize how beneficial the team would be to the school. make sure that you have all of the finances worked out ahead of time (paying a coach, buses to comps., etc) and a place to practice. if the gyms are busy, you may have to find another place. our team practices in the cafeteria.
7.) Any ideas on where we could by costumes or uniforms?
just try to get different costume and uniform catalogues...it really depends on what you are looking for. it depends if you'll be performing jazz, pom, high kick, hip-hop or novelty, for what types of uniforms to get. price is important, and also, if this team will perform at football and basketball games it will probably need to be in your school colors.
there are many more sites than this, but here is one uniform site
www.varsity.com . . .
8.) DO you no of any competitions in the New England Area?
www.varsity.com . . .
this shows some UDA competitions from last year (look under northeast)....
upainc.net . . . that is the site that shows UPA regional directors, and you could get ahold of one in your area who may be able to help you. also, in wisconsin there is the WACPC (wisconsin association of cheer and pom coaches) that holds many competitions including regionals and state and you may have a similar association in new hampshire or new england.
www.ayosinoffcheerdancecamps.com . . . also, here is the site of a 15th annual cheer and dance competition
hope this helps! good luck with everything!
