Hello! Good to see another signature designer around. Let me know if you'll need help in anything. I'll be happy to help.
However, you should stick to a price after you get into market as people tend to lower their prices . This may end up with your work being undervalued . I would be glad to review your service .
Sadly, most signature designer now lower their prices without thinking of the effect of it in the market. It takes hours to design a good signature and because of some designers lowering their price too cheap, it's getting harder to get clients. I know there's a competetion in the market but they should atleast consider if the price their offering is worth the time they spend in designing.
