Would anyone who knows how to disassemble and reassemble or repair the piece be interested in buying from me? I don't want to deal with this anymore. I would give a greatly discounted price on it.

PM me if interested.
I sent you a pm with an offer to assemble it for you if you are interested in keeping it.
For all others facing the same problem with this or another puzzle you need help with assembling, please pm me. I've put together quite a variety of puzzles. I won't charge anyone for assembly. I take apart my own puzzles and reassemble them for fun.
