How old is your daughter? Where is dad in this picture?
The likelihood of someone cheering or tumbling professionally is low. I live in Plano where Carly Patterson and Nastia Lukin trained. My daughter did tumbling training at that facility. It is a very competitive and expensive sport.
My now grown daughter was in cheer many years through the school. It is a very expensive sport and we were not in competitive cheer which can be wildly expensive with all the travel, training and injury costs.
Our teams did fundraising for new uniforms and some expenses AS A TEAM but we still spent about $5000 out of our pocket per year. The cost increases each year as they get older for more specific training, etc.
We did have a scholarship fund and part of the fundraising covered the scholarship money. Our fundraisers were through the team (and parents) working hard to sell concessions, prepare and publish a football program for each game which included a lot of sales for local advertising, teaming up with football, baseball and basketball teams to hold silent auctions, ,etc.
In order to get a scholarship, there had to be a true need. School administration as well as coaches were involved in those decisions. Those decisions had several factors... family need, grades, etc.
I know it is hard but the bottom line is if you can't manage to afford it then it has to go. People do not seek out individual sponsors. Sponsors want more out of the deal that just paying for 1 persons training and expenses.
You might look around to see where you can cut cost at home, sell something you no longer use, stop going to Starbucks if you are a regular there (that adds up VERY quickly). Talk to the coaches and administration to see if there is a scholarship fund you may apply for.
It is sad but when there is something you can't afford such as cheerleading, you may need to stop. Think about the future... namely college savings plan so your daughter can get a good education.
Best wishes to you.
