Mac Authorized repair in Hollywood area

It looks like I may have a MAC hardware problem. Can anyone recommend a good repair place -- better yet, one that makes house calls since this G5 is VERY heavy. In the Hollywood area.

Does anyone know anything about Mac Hollywood?

Do you have apple care still, If you do and you have a tower, they should (they used too at least) do house calls, this may no longer be the case as they have also dropped the hourly rate of warranty repair (from ~80 to ~20/hour thanks apple)

My apple care ran out earlier this year, in January. Maybe there's a way for me to extend it or to purchase an additional apple care contract.

I've heard that authorized Mac repair companies may be a better way to go than getting Apple to repair it.

Any thoughts on that? Thanks.
