Need Help With My Site - $$$

I have a simple B2B site and I need someone who can make a user database where vistors can register, get a password and login to the site. Once they've logged in I need an autoform made where their will be different products listed with an empty box next to them where the client can specify the quantity that they'd like. The completed form then gets emailed to a specified address.

I've already purchased the domain and wrote out all the copy, I just need someone to do the user db thingy and form and maybe edit up a free wordpress template I like into shape.

Hit me up if you can do this asap.

What is your budget?
