The websites which you may sell on would depend on your genre and instrumentation. I would make sure you have the right to arrange the piece you are selling. Usually you can do this by reaching out to the original composer, family estate, or publication company who owns the right to the original song. Once you reach out to them you can work out a percentage deal on selling the arrangement. Some music publication websites already have the rights to most songs and they will offer you their set rate which is usually something close to 10% for the arranger. Examples of this would be, sheetmusicplus, JW Pepper, Hal Leonard, etc. If the original song is in public domain, you can sell your arrangement of it for 100% profit on your own website or platform.
