Hi,
I sell printed items and graphic design on my website. (www.prakprint.com)
The printed items are already set up, but when clients order graphic design I usually require a deposit upfront. (Which could range between $75-$500)

Every design-only project price is determined after speaking to the client.

Is there any way I can charge a client $150 or any other fee by sending them a request before we design, with my specified amount? Or any other suggestions?

Any help would be great. Thanks!
