Advice on printing names and numbers online??

You will need a heat press.
You can order heat applied screen-printed or vinyl names and numbers transfers.

If I'm reading this right, you are selling the shirts to the team members and their friends/family
and then giving the team $10 from each sale?
If so, they are getting a great deal.
For no work and investment/risk on their end they are getting 50% (all profit).
Won't even go into additional paperwork you have to do come tax time.

Sell to the team and they can add whatever markup they want when "They" sell to
the members.

Logo tee, $10. Oh, you want a "Custom" name & number on that tee, be another $5.

I press names and numbers for screen printers, sporting good stores and embroidery shops all the time. I also run DTG prints for them. I send screen print work and embroidery jobs back to some of these same shops.

My advice is to call around in your area. I am sure you will find a shop with a heat press that would be glad to run these for you. I am also sure if you ask the right questions you will find a shop with a heat press that would love to build a relationship with a local screen printer.

From a business end it would be easier to sell the shirts to the sports organization for $10 and let them handle the sales and distribution to the actualy buyer. If this isn't an option you will want to get a reciept for a donation to the sports organization (Hopefully they are a 501 C non profit). Sell the shirts for $20 and then at the end of the sale make a single donation to the non profit sports organization - Since you are making a donation to the organization ask about hanging a banner at their facility, getting a link or logo ad on their website or even a single email blast to thier membership announcing your donation.
