Hi! I'm Eddy, a gameplay programmer working in Godot and Unity, and I led a six-person Godot team. Building a game end to end for your storefront sounds like a good fit; which engine would you want the game made in? I run ThirdAngle and also take programming contracts, so feel free to reach out if you'd like to talk it over.
