I’ve checked two of yours (I’m actually secretly interested in one of them
) but to give a brief summary:
C# gig, it is very well made. I think the only thing you could benefit from, is to create a short video to deliver visually an idea why people would not only want to learn C# but also from you!
As for your IT solutions gig, I’d say - give more description to it. As in, what kind of issues you are capable to deal with. Very often, clients don’t even know what they need. So when they begin to read through your skill set, they might be like: “Oh, this is what I need!”. Because some of them can’t see sharp anyway.
Anyhow, good luck in your journey! I see you’ve only started your long adventure on Fiverr. First and foremost rule - don’t give up. Give it some time to blossom.
