Graphic Designer to create Headers/Logos

Looking for a professional and experienced graphic designer who can create logos/headers for us and have a long term business relationship as I'm always in need of logo/header design and other little jobs. I'm paying $30 per header which also includes the logo, so you must create the header + logo and all I'm paying for it is $30, but sometimes I just need a logo, so please don't bid no more as you'll be wasting your and my time. I also need images modification and editing, and I would like to pay $5 for it, so let me know if you can do that as well. Please DO NOT RESPONDING without reading through the listing, and send me your sample works of your headers/banners that you have created, thank you!
