This kind of job will be good experience for you as a first-time DIY home project.
As Steve: says, get a GOOD book. (And as I always say - Spend some of the money you're saving from not having to hire a Pro and spend it on a GOOD book. It's money well spent!) The GOOD news is you really can't mess up if you're good at following directions. So read twice, MEASURE twice, and cut once!
Welcome to the DIY 'world'. And if you have any ?'s, you know where to find 'us'. My best to ya and hope this helps.
