While it is possible, I would not use them for selling services. The platform itself is focused on selling products or goods that are able to be delivered electronically in an automated way. This makes it so that items such as product keys or guides are the ideal items to be sold through this platform. For selling services, a freelancing website would probably be much better, albeit I have not heard of any reputable one whose main focus is Bitcoin clientele. What you could do is find any reputable freelancing website and market yourself there in such way as to make it obvious that you accept Bitcoin payments on top of, optionally, fiat. The disadvantage to this is that it is not automated, but when it comes to services, automation is usually not what you are looking for anyway.
Thanks for your response. Great Insights.
Though I am already using some freelance websites, most of them don't allow you to take payments from external options and you have to go through the option they provide on their website.
For now, I was only able to find OpenBazaar and Rocketr that allow you to take payments in cryptocurrencies in exchange for your services.
I am really surprised to see that with tons of ICOs no one came with something like Fiverr, a gig based website to connect sellers and buyers, especially for freelancers.
Or maybe most of the ICOs are just concerned about raising money rather than making an actual product.
