Hi and welcome to the site. I suspect from your post that you have no business experience? If so, please let me sell you a business for the knock-down price of $100,000!
But seriously, you are most likely to get ripped off, so does it matter to you who by? And even in the unlikely circumstance that you do not buy a turkey, what likelihood is there of you running it successfully? There is a lot more to running a business than just having the capital to purchase one.
Do you know what kills many/most companies? Over-trading. Do you know what over-trading is? Then there is over-reliance on one major customer. Or one product. Or lack of focus (too many products)... Then there is the trading climate. In a favorable climate, many poorly managed business are successful, for a time. But in an adverse climate, many fall by the way side. A good entrepreneur knows when and how to retrench and survive, and when to push the boat out and grow. Do you?
Turning to your question, what do you mean by "This business generates around $80,000 per year?" Is this figure the turnover, gross profit or net-profit?
What are the projected earnings, and how realistic are they?
