Looking for a php script that allows store hosting

[transitnetwork]

I'm looking to start an online store hosting service like 1shoppingcart.com, I am a php developer but I'm wondering if there are any scripts out there that do this already so I don't have to start from scratch.

Please advise, thank you.
