Looking to pay someone to create a large part

Some electrical (not Fritzing related ) thoughts on this, which if the boards are done may be too late. I don't see current limiting resistors on the various led leads. While values may be difficult (because you likely want to support multiplexing) experience tells me (because I do it when prototyping ) that the kids are likely to accidentally connect 5V to the led pins which will likely burn the led out without a current limiting resistor in the way on the board (which may be there, and just not obvious in the photo). Sockets for the leds so they can be replaced when this happens would be one solution.
