There are full of signature services. So what can you bring new ? I see your account is fresh here so this is not stable for trying to make a deal but I wish you good luck with your service.
Every person has a different way of doing the same thing. No matter how many people make the same signature, but all of them will look different, and I'm sure my work will be different from others. And about the account, no one needs to worry about that as long as there are escrows on the forum for keeping the deal safe for both sides.
Anyway, Thank you for wishing me luck.
