wow... 1 cut lol. There is a formula you can look up online. You have to use real proven numbers though. Sign a full disclosure and have them show you tax records. No company that large does their own taxes. Also, bank statements. Take a look at those. The equipment isn't worth maybe 10-20% retail for everything to the last shovel. But you didn't ask how to do it.. you asked how much would I pay... $885,000.00 given the numbers you put out there to include everything. I wouldn't pay it all up front. I would give him 33% up front and the remainder would be paid with net profits after my new additional MODEST $35k salary and also the remainder would be dependent on the attrition rate. so potentially 885k but not guaranteed. And that's a very low offer. I would probably fire all employees and bring in my own crews as well. The owner and some foremen would be required to stay on board for 6 months with a company this large.
