[Custom Form Submit]

I'm wanting to add a custom form submit to my website, one identical to this

how hard would that be and how much do you think it would cost me?

[Creating Website - Classified Like, Help appreciated.]

Hey guy's, I wanted to create a website - I got the domain and I can design it but I really have no clue with making it function properly. Basically the website is a little bit like craigslist but MUCH MUCH simpler. It's basically a Buy/Sell website for online currency to a certain game.

1 = Main page, the main page will have two large buttons on it One directs you to >Sell Gold, the other to >Buy Gold.

2. Whatever options you choose you will be prompted to Create an account

3. If you clicked on Buy, after you create an account you will be able to view the seller listings

4. If you clicked on Sell, you will be prompted to create an ad.

 

 

That's just the basic skeleton of it, I would love to add more later but I want to know how difficult it would be to make something like that.

Any help appreciated
