..who can do this locally (I'm in the N Tampa area)?

 

You want the conversion or the retrofit? Conversions are just kits that are sold. Retrofits are the way to go. They replace your halogen projector with a projector that was designed for use with an HID lighting system.

 

if you do the install, please quote an installed price for both systems, and provide links to the systems you're proposing.
thanks
