I have to say, your gig looks pretty good. The lighting is a bit off in some of the example images, but your description is well put together. If you remove the highlights and just keep the bold and normal text, you should be fine. Just be careful when offering unlimited revisions, because people will abuse those. It’s best to offer 1-3 to avoid being taken advantage of.
If possible, try and get a friend or family member to buy your service. If they’re happy with what you’ve done, they can leave a positive review. Just be careful not to tell them to leave a positive review, because that can be seen as feedback manipulation. Once you have at least one good review, buyers on Fiverr are more likely to trust you and come to you. It will take one hell of a lot of time, though.
P.S. There’s a spelling mistake in your gig title. It’s “boost your sales”, not “your sell”. Just letting you know
