.ascx Redesign

I have three .ascx files that need to be re-designed with a clean and professional style. The .ascx files are from a module used in DotNetNuke. Understanding of DotNetNuke is not required. The module is from [login to view URL] and is the UserGroup module. This module contains several forms and datagrid pages that I want to have customized. Work would require using javascript and CSS to enhance user experience when interacting with the pages. The goal is to have the style clean and professional with enhanced borders and background images. The input fields would have javascript functions that would pop up information related to the input field.
