You are going to need a hosting provider that has PHP or ASP capability, depending on the type of programming language your developer uses.

There are so many programs out there in the GPL (General Public License) that you can use to start from, but you really need someone with programming knowledge.

You can start with http://www.dailyrazor.com has a hosting provider. They are VERY inexpensive and have MANY capabilities already built in to your server.

Good Luck!
