It's similar to a typical gig, but it's exclusive—only certain sellers can purchase or locate this gig. I've joined and created the gig, but haven't received any orders yet. It just began a few days ago, so I'm unsure how it will play out.
In my case, the buyer was forcing me to do more 5 pages conversion from Figma to Wordpress at a very low price. I refused to do it and now he added extra 5 days on the last delivered order. He is trying to find problems in my work. But at the first order, he was so happy. I am not sure how long I need to suffer.
