For the sake of privacy on this forum it looks better to have it done that way. Here is a decade of designing skills. I don't intend to have this as a long term service here. Will only do a couple of work to collect some cash. The work doesn't have to be related to crypto at all the reputable member may have or need to launch a side buss.
You can't really tell, you should have anticipated that your service will have demand here if your design is good, but have it your way since you already told us that you will do a couple of work, and collect cash and you don't have this long-term service here.
What you're offering is still good only
pay what you wish only after the work is delivered and you are satisfied!
But you did not post the price of your service, for your potential client to see if it's competitive as we all know there are others who offer similar services.
