Hi, I found your advert and was wondering if you're still looking for a designer. It's hard to give you an estimate on the cost with the amount of detail, if you're interested DM me more details, e.g. content, if I have to write the copy, sizing, and how many you're looking for I can give you a much more accurate estimate.

Here's a link to my Dribbble and Behance for you to take a look at some of the design work I've already done.

Hope to hear from you soon!
