"Hey!
I am James, creator of Bag. I'm looking for someone that can design something for my architectural firm. I want to have a business card for myself. We primarily use the color blue (#42cfff). Can you do that?"
Creative idea. I really like the grid lines and the font you used for the logo, its very simple and neat. The contrast that you've made between the logo and the background looks neat as well. The problem that I do see is that there's nothing on the card to indicate what kind of company it is besides the grid lines. I think that it would be nice if there were to be text that said "architectural firm" or "architecture" somewhere.
