I'll tell you what you will get for this.
An amateur coder trying to get a few jobs under his/her belt who will code up an insecure application for you, then by the time he/she really knows what they are doing, rather than come back and clean up the mess they've made they will just disappear, and (try to) forget the project ever existed.
Oh wait! You already have that!
And I'm not even "that good." :-)
If you want a coder to stick with you, the answer was posted right off, put yourself in their shoes and make sure they get enough compensation to focus on your project and at reasonable conditions. $200/month won't keep a "programmer in your pocket." We have to survive, and that means, okay, I'll take your $200/month, but that means I need to do other work, and this other work is going to subtract from time when you really need me.
A footer link "designed by Woo Hoo I'm great" is only something an amateur does. This is not how you collect clients. It's similar to "This website best viewed in . . . "
Here is a second option for you.
So you can't afford a full time programmer. Who can? But what you can do is work in a set of directives and a monthly budget. So if you throw $200/mo at a qualified programmer, what you can start to do is line up 12 tasks, one for each month that will be reasonable forward moves on your site. Get someone good at things besides programming as well.
I can guarantee you your first month will be just the coder taking time to fully explore the site. But at the end of a year, you're only $2400 into it and your site should begin showing results . . .
