The quickest way to get started is to buy an Hourlie. An Hourlie is like an ‘express job’ where you instantly hire someone to start working on the job they advertise in their listing. Because Hourlies are for smaller jobs it is like getting a ‘taster’ of the person before giving them a larger piece of work. Once you are convinced that the Seller is delivering what you want you can very easily carry on working with that person. To arrange for follow on work all the Seller needs to do is send you a custom proposal in the same WorkStream.
Alternatively you can simply post a Job and start getting custom proposals from freelancers from the start.
See the Buyers guide to getting started for more info.
