X2 on taking it to a pro.
if you've even done a few minor patches before, it might be fun and worthwhile to take on something like this. but removing a glued in floor and replacing it is a pretty major league job. even if you know what you're doing, if you mess up bad, you might find yourself in way over your head. take it to a real repair shop and see if they'll let you watch/assist.
i'm not from idaho, so i have no clue of any good shops up there. gotta be lots of buzzards with recommendations tho
if you do remove it yourself, try doing an easy day run with no floor!! you might love it!!
