Buying Sci-fi wall/set

[mushroomsoap]

I'm looking for items in the sci-fi set, specifically the sci-fi wall. I'm willing to pay up to 600k bells for the wall + another item for the set. I'm also open to taking offers on prices.
Thanks!! The wall is top priority for me as I already have most of the items in the entire set.

I can sell you the wall for 2m
