I don't have telegram, but I am curious what you're looking for in a partner.  You seem to have a very unique angle with burning the original artwork.  I can't say I've seen that before.  I wonder if allowing the buyer of the NFT to have the choice of burning the NFT and getting the physical artwork or burning the physical artwork and keeping the NFT might be an interesting twist.

I see you're using an opensea contract.  It would be possible to do a custom contract and have a website with a minting dapp where users could pay to "mint" one of your paintings into an NFT.  Did you have any specific ideas for what you'd want a partner to provide, or were you thinking more along the lines of a promoter of your existing collection?
