You can always tell hubby to tell her that he spoke out of turn, that he hadn't checked with you first and you can't o it after all. Or, as lauriejo suggested, have her find and buy what you would need. She may end up not doing it, or at least she would find out this stuff isn't magic that just appears for you. Have you discussed prices? That may be a way out, by giving her a realistic price of what everything plus your time would cost. Uglycook did a really nice piece on pricing in another thread.
