No problem,
If it helps, I purchased a Retro kit that allowed me to install on my own but with no wiring necessary, into a canopy that I built, well a friend built while I cleaned his shop
If the ad doesn't work for you let me know and I can put you in touch with the ebay seller I dealt with. I believe that I paid about $285USD for a dual 250w PFO Ballast and 2x250w 10k Venture bulbs.
I know that others may have good suggestions for reasonably priced pieces as well, but this worked very well for me!
