how and where to find gigs to complete and get paid
You create gigs yourself which explain what you sell. It is totally up to you to make them look good, be honest, write well and read through the forums and Fiverr help. If buyers believe you and like what you offer they will buy from you.
You say in your profile that you are a writer but you seem to have trouble writing fluent English so writing gigs may not be a good choice for you. You can go to the Fiverr home page, look at gigs there, then try to think of things you can really do very well. You will not be able to honestly earn money consistently here by offering gigs you aren’t great at.
