I'm looking for a pre-built or custom solution similar to, say, an Envato marketplace like themeforest.net--that is, a site where people can go and upload their (digital) products and sell copies of them to people who visit the site.
Can anybody help me out? Is there a pre-built solution for this? Is finding a programmer on some freelancing site the way to go? (If so, which?)
Thanks so much for your help.
