Want to Buy - UK Small Business

Hello everyone,

As is quiet evident from the title. I’d like to acquire a small business in the UK - I have no idea where to start (really).

I’d ideally like to buy off a retiring boomer - someone who’s be willing to stay on for 6-12 months to teach me the ropes and help me transition into the role.

I’d also like the structure the deal in a way where I’d have to put the absolute minimum down.

I don’t know honestly - any advice would be helpful please.
