We're a non-profit niche social networking company serving a minority group. We are have a volunteer working on marketing our pending web social network app, however as CEO, I'm looking forward to hire an expert in web marketing tactics mainly to help make our launch a successful one. The main role of the person is with helping us plan with our marketing strategies as well as helping us implement them. We are very hard pressed with resources, what's the best way to hire one which we can afford, at say a rate of $10/hr or even less. I really do not have trust in freelance websites because of the poor quality I've received from them so far.
I agree with all of the previous answers and would recommend you spending as much as you possibly can on a marketer.
True marketers care almost obsessively about making sure they can directly tie their efforts to results.
Marketers that confidently ask for a large amount of money do so because they confidently know they will generate a lot more.
