Can you sell FBA Business

Can i sell my FBA business?
I work it myself with couple of part time staff.

I have had meeting with Empire Flippers, but because i don’t use 3PL, they said its not what investors are looking for.

Its a good steady business with good annual turnover.

We want to retire next year, and would go against the grain of all the hard work just to wrap it up.

Any advice appreciated.
