Well the thing is I am a passionate Unity game developer and I made a gig on fiverr for Game Development but it has been over a month and no one has placed any order. This is something that is not very astonishing cause I am a seller with no orders, ratings and reviews so why would someone buy from me in the first place when there are a lot of other sellers available. The thing I want to know is what triggers a person to buy from a new seller? What will make a person want to order from me who is a highschool student and has no selling history?

Please let me know that what can I do to make sure that I get orders.

Hi! In indies the founding person is mostly a programmer themselves, then programmers are the easiest to find and often contribute for shares. It's also a longterm part, not a gig, unless you are doing something super small. Artists (pixel, concept, 3d etc) are the most sought after, then music, but also much less. If you want a programming job- consider commercial offers in web development or a career in engineering. If you want money from gamedev- specialize in graphic assets. If you want programming games- make your own or tag into some team (I can give you a share, but after kickstarter/launch). If you are really hardstuck on the idea- portfolio+promoting should get you something eventually.
