If you can't find someone to respond to your requests, chances are your request itself isn't drawing enough attention.
Personally, if the request says $50-$99 or less I won't even open it unless I see that the member and their website are serious enough to where it may be a good relationship for ongoing work here and there.
I've only seen one request from you:

Aside from the fact that you're only paying $150, i still have absolutely no idea what you said or what you need, which is probably why others didn't respond as well.
I've told people time and again, be as descriptive as possible. With as much detail and clarity as possible, it leaves little room for error and interpretation.
