Design Gift card/wowcher for beauty salon and envelopes for the gift card too.wan to make advertisement posters too for front window."as

I am looking for a designer to create gift cards, envelopes, and advertisement posters for my beauty salon. The design style should be elegant and sophisticated. I do not have any specific size preferences for the gift cards, envelopes, and posters. However, I would like the design to be modern and minimalist. I have a general idea of the color scheme and design elements, but I am flexible and open to the designer's creativity. The ideal candidate for this project should have experience in creating elegant and sophisticated designs for beauty salons. They should also have a good understanding of modern and minimalist design principles.
