Step by step "How To" for buying a Fiverr service

Why is there no step by step explanation for how to buy a gig? I want to have someone add my Twitter tweet to be sent to their followers. I see how to buy (pay for ) the gig by clicking on the Order Now button, but how do I send the gig seller my pre-written tweet? Am I supposed to pay first, then a window opens for me to enter my tweet text? Why no obvious “Here is how you buy a gig” page?
