Btw, I'm a graphic designer, I see you have a logo and a banner with a message. I can do a logo and a banner for you if you want, its free, you don't need to pay for it, and if you like it is yours to keep, I just feel like I want to help and aport with my knowledge in a way im good at it, so if you are ok, just let me know.
