You can contact any user whose skills you interested even in the current state of the service. Later, when we put in there a smart contract, rating system, arbitration, etc., customers will also be able to freely communicate with the performers. The platform has no interest in the form of commission or fee, but users have an interest to increase their rating, secure the deal, use the service of decentralized arbitration in case of a controversial situation, get more bonuses after each transaction, which they can use eg to purchase tools or software from our partners, etc. That is the goal - give more advantages to freelancers eliminating the need to pay services' fee and shifting it to partner companies.
