Hi Stephanie. Congrats! I work with a lot of school-aged athletes as well (individuals, small groups and teams). If this is your first contact and proposal with this school, you may want to make it reasonably-priced to give them (and you) an opportunity to see and show your stuff! I would consider pricing it slightly below your ‘market’ price for a small group of similar size, and let them know in your proposal that you are providing this ‘initial service’ at a slightly reduced rate (that way, if they/and you decide to continue or expand beyond your initial 6-8 weeks, you have the ABILITY – but not the OBLIGATION to raise your rates to your ‘normal’ rate or not.
Most public schools have a fairly limited budget, so by offering a slight discount, you may peak their interest. If this is a private school, their situation may be a little different.
I hope that this helps and good luck to you!
