Modify Business cards, Letter headings

We need a great graphic professional to modify our current business cards, to change the phone numbers, emails and include the logo and web sites. The work may include adjusting the colors and resolutions. The business cards must come in formats that will allow us to insert our staff name, phone number and email without distrubting the graphics and logo. In additional, the choosen professional will convert some current flyers to html email banners with hyperlinks. Money will be paid through escrow. Only professionals who can commit to long term relationship need to apply. We will need this individual to continue to help us make banners, and html emails...so TRUST is important. Note: This is a very small project.
