I probably go one of two routes...

1) Rip out everything myself, hire out plumbing work, and then either
find a cheap handyman or a buddy to help remodel the entire bathroom.
If you just update the vanity but not the rest of the room, it will
look out of place. When I did mine, just make sure the toilet and
floor go in first. This way you can at least go to the bathroom.
(plumbing should only be a day)

2) Start writing home makeover shows with a really good sob story. Get
creative. Deaf kids, handicap wife, and caring for older parents; all
while being laid off from the manufacturing plant that is posioning
your house. They love a good story.

Good luck
