I want to merge my friend's carpet cleaning part of his business into mine

[SamIam]

How would you approach the subject without making his business sound insulting

I really appreciate all you've done for me over the years, and I would love to help you out like you've helped me.

Would you be interested in me taking over your carpet cleaning needs and of course what would be the best deal for both of us?

You get to feel him out with out being insulting.

Say something like it could be a win win for both of us.
