Help Regarding a Directory Site (urgent)

I want the i allow users to post the following three things

1-Title
2- A image
3- about 200 words writeup
4- A Link to their site
5- A Price

All of above are compulsory .

Now the problem,
The post will be shown as image and description , I want a buttong saying ” Visit Site ” Or anything else that will point out to the site submitted by the user .

i don’t want that a visitor clicks on the title and is redirected to the User submitted site .
what i want is that when user clicks on the title he comes to a page (See the user submitted image and description ) and then click on a prominent button (that will show price and ask user to visit site )that will redirect to the user submitted site link .

The problem is that i can’t find anyway to show that button that will go to user submitted site and show price .

I need urgent help on this .

PS: I haven’t started setting up this fuction to my site , Its a wordpress site and i want to add this directory to a subdomain or a page e.g
example.com/directory
or
directory.example.com

Please recomend which plugin i can use that will allow me to do that .
or which script i should use ,

I tried searching for business directory plugins but they lack the price option ,

I also want to have my own theme so kindly something related .

Thankyou
