I am trying to create a marketplace site similar to Elane and Getafreelaner, or even Flippa. The site won't be about freelancers bidding on a job or bidding on sites for sale, but all the functions on my site will be similar to the sites pervioulsy mentioned. What is the best script to use for my site? Has anybody tried PHP Pro Lance, is it any good? How easy would it be to change the purpose of site using PHP Pro Lance so that the site is about bidding on something else rather than freelancers bidding on jobs? Or should I have designer create a custom script from scratch? How much would it be, and how long it would take? Thank you in advance for any advice.
