Partner hates my plants. If I were to sell this monstera what could I expect to get for it?

I’m southern U.K. based. If I were to sell, what would a reasonable asking price be?

It’s my pride and joy, but it’s massive and my husband hates it because it’s taking over our room.

It’s about 3-4 years old. About 4ft - 4.5ft tall. The leaves are MASSIVE, and it’s currently sprouting a new one.
