There are two definitions for the word "banner".
If we are chosen to develop your website, a header banner is automatically included in the project price. If you need the other kind of banner (a small graphic to advertise something), we can do that as well. If you let us know during initial negotiations that you need ad banners we can quote them into the project price. If you want them later then they will go under our hourly rates. For the people needing ad banners by themselves without websites, you must pay a flat rate.
If you have a concept of a banner in mind (either header banner or ad banner) we can take your concept and clean it up, improve it, make it sharper, more elegant, more professional looking, cleaner, just all around better than the original concept.
