I’m here on fiverr since march 2020 (one month ago) and I can’t get anyone who buys my gigs:(
Your minimalist logo design gig is in one of the most competitive categories … and I found your main image on another site very quickly. You need to look at your competitors, make yourself stand out from them … and don’t use readily available images from icon sites …
The reason buyers willing to buy your service because they want it or because buyers want to help you.
So we as the seller just can do promoting our services.
Even if you are good at it, if buyers don’t want to buy the service from you that’s mean you have no sells.
So my suggest is keep trying to convince your prospective buyer if you still want to try.
