Hi there,, I'm Matt Sergei (do call me Matt, please) and I like basketball too -
used to train it and my son and daughter have been too (until she got ACL on right knee, just today we got a surgery schedule on next Wednesday, still she hasn't given hopes to play basketball all life).
Now - the budget is too small for any serious (yes, even simple) game development. Have you researched what would "drive" kids to play your game? Have you seen and play Basketmania (I have it on this MacBook Pro)? Those are games costing tens of thousands dollars to develop.
When you have that sorted out (main idea, maybe just simplified shooting like Basketmania) and more serious budget to consider for development time required, you'll get more relevant offers.
For me - yes, sure, would be able to help for much less money just for the love of a game yet I'm incorporated and my rate just has to be $150/day. So do much less free, donated or discounted work as in the past.
Regards and hope you're safe (and keep love for the game of baskeball!),
Matt
