why my gigs not salling from start
I think you need to go look at some other gigs that people are selling. Look at the top sellers and then get some ideas of what a gig should look like.
Data entry and copywriting should be two different gigs. Also, you need to actually write much more of a gig description. which part of the problem is your English is not so good and there are many mistakes, so if you want to have people hire you for copywriting you have to demonstrate that you can write to begin with. You also should say what kind of training or writing experience you have.
Also, the whole I will do anything you want to make you happy doesn’t really work. Are you selling computer programming? It’s not clear at all, and that photo makes no sense - did you draw that? ARe you an artist?
You should also consider changing your profile photo as well.
