Interesting discussion. We started a shop in a town were there was already a
sign business, he wanted us to buy him out at $120k. We made $10 k year one, then in year 2 made $25K. Our competition wanted $60 K to buy him out at the end of year 2. Last year we delivered a huge marketing plan, in an attempt to steal all the business from him. We succeeded by putting the competitor out of business in Dec and made $70k net last year in the process.
I would think that unless you have a real good backing, and plenty of time, the $30K he wants for the business is cheap. Go on your own and it will take several years to develop the business. In the cost he is asking there is the hidden value of not having competition. So in you cost analysis take this into account, there is more to buying than values tied to equipment and hard assets. He also has a customer base and a location.
