Perhaps the problem is that you seem to sound desperate in your profile and gig description, not confident and like a professional? You’ll do it at a low price, you’re always online, unlimited minutes of footage & up to 60 minutes of running time for $5… And in another gig you offer up to 60 minutes of footage provided and to make a 1 minute video, also for $5.
On top of that, your gig descriptions are very short, tell what you’ll do, but not what’s the appeal of it all.
In short, it looks like you have no idea what you’re doing (in terms of running your business here) or how to present yourself as a professional with your profile and gig descriptions. You’re not giving anyone any reason to choose you over someone else.
