**The budget is a placeholder.**
An Upwork Enterprise client is looking for an expert banner designer/developer who can create and code dynamic (live) banners.
For an explanation of dynamic vs. the more standard animated/rich media banners: http://www.quarticon.com/blog/dynamic-vs-static-whats-the-difference/
If interested, please submit a link to a site which displays a dynamic banner you have created and attach the spreadsheet containing the extracted banner form data with your cover letter.
