How much money can I make through YoCo?

It really depends on you. If you are an individual with readiness to help others in different ways, there is really no limit to the money you can make through this platform.

You can take as many requests as your time permits and you can demand a fee that you think is suitable for each request. YoCo does not interfere in this at all. 

However, please keep in mind that the fee you demand must be competitive since there are other providers quoting their price too, for the same service. Your fee must be commensurate to the effort you have to put in for delivering the service and only you can decide on that amount.
