interesting concept and nice + fast website, you need more promotion to get as many as freelancers and people who need help from freelancers
cheapest way to promote is from bitcoin ads network and Pay To Click programs. You can try that method for promoting.
my suggestion is add "about" and "privacy policy" page in your website, these page will make your website more professional
i'll take a look and possibly need freelance writers in the future, i will try to search it your site.
Good luck
