If your cousin has a mill talk with him about a share deal. You supply the wood, he supplies he milling and you split the profit. Should at least double your money. I would expect a 10 fold increase myself.
We are starting a collection center for those who only mill small numbers. Here we will grade and restack to sell to the highest bidder and then split the profit with the owners. If the owner is prepared to wait the 6 to 18 months for their return then we can up their profit form a few hundred per cubiv meter to 6 or 7 hundreds.
Dont know about your local but here it seems to be stuff the small guy whenever possible and still have the customer pay though the nose because the hardwoods are getting harder to get. Some traditional mills are quoting times of 6 months to get a select species specific hardwood.
And if you do descide to buy a swinger the normally pay for themseleves within 3 to 4 months, 12 months if your just doing weekends.
all the best with your descision.
