What do you guys think of this App (iFreelancer)

Looks pretty good. You should consider selling this as a stand alone script on something like http://codecanyon.net

Yes, I will sell it on CodeCanyon.

Things asking for trouble -> Create ticket, set status to "Pending" or whatever -> Go to options -> Delete status from list.

Yes did that, the status has been deleted.. But new status can be easily added/changed...

Can you be little more specific with what you meant?

I like it. Other than bootstrap for frond end, what did you use for backend etc ?

PHP and MySQL
