"I would like a light up with sound . Can you Busters reco me a seller or maker i can buy one from ?"
No one makes the packs on whole to sell. You can purchase the parts and there is the GBfan web site GBfans.com that has all the information to build your own pack.
Having built a couple packs in the last year, I figure currently you can build a nice high quality fiberglass pack with full lights and sound for about $ 800 in parts. Once you have all the parts assembled, I have popped my two packs together in less than two weeks with a few hours a day in working on them. Obviously it is easier once you have made them and are familiar with the parts needed and suppliers out there.
