So you just want a ready made store and not do any of the work doing research, finding proper equipment, or developing a brand?
I don’t mean to be rude, but if you want to make money there’s plenty of other ventures to go into. if you want to own a fish store, im sure it would be more rewarding to set it up yourself…
I say this as someone who has worked at fish stores for almost a decade, and is working on opening one. Do not do it if you want to make any good money. And don’t do it if you think that it’s a business you can just buy into with very little experience in the industry.
