Something similar to Fiverr or even Seoclerks would be brilliant for a website to be able to work for others in exchange for bitcoins. I myself have been looking for something similar for a while and everything I find is either not busy enough to warrant bothering with or it does not look too professional and may be worth staying away from.
Bump, sorry for the major Bump. But couldn't help notice this comment.
We have implemented such a solution at www.cryptogrind.com
which offers multi-signature escrow on every order.
Security is also unrivalled on our site as we use technology which accesses the blockchain directly without use of hot wallets, basically we never store your bitcoins or private keys in any wallet or database.
You can checkout the services page here, which is now gaining traction: We have only been live now for a month and we have had a few escrows successfully complete through our platform.https://www.cryptogrind.com/#!/services
Listing services is free and you can list as many as you like.
More information about the services platform can be found here:http://blog.cryptogrind.com/cryptogrind-services-platform/
We have really spent time on making it the most user friendly and secure platform for our users and welcome any questions.
