Keep searching on Google and evaluating the products offered in the search results. You know what you want far better than anyone here.

There are some really good options available if you do a little bit of searching around. Personally I like PHP Live! Support [ Live Help Live Support Software Download ]

I highly recommend livezilla. Its free. You can also subscribe for its premium features.
