You should think about selling clickbait. - You did well here, very well.
Please buy logo 5 dollar
Begging for sales is a good way to make sure that nobody buys your gigs.
You only have one preview image, which has some major graphical problems of its own.
You are really overselling the value of what you’re offering. If the logos are anything like the preview image, they are certainly not high-resolution, they most definitely don’t appear to be vectors, and your description again is full of contradictory information.
TL;DR I would suggest honing your graphic design skills and lowering your prices to the minimum, and definitely increase the value that a buyer gets with each package.
