I am planning an online marketplace for professional services (along the lines of Fiverr but for a specific niche market).
I found several web developers who could build a custom web app for me but of course at a steep price. I was wondering if there are any feasible alternatives to a completely custom built app. Perhaps using a content management system like Joomla, Drupal or WP or an open source marketplace software. Any suggestions?
Can anyone point me in the right direction? Thanks!
