I tested everything, creating some fake users to see that everything worked. And it is. Put some great text, some great reviews. But now I'm starting. No reviews. No freelancers. No "We have x numbers of Freelancers!!!". How do I start now^
Market on popular sites like Upwork.com and others to help freelancers find new resources. Approach bloggers in the category - try "side hustle" as a keyword and offer to write a post and let them know about your value proposition and you are now welcoming frreelancers. Explain what's in it for them - good luck!
