Berkswell Yorshireman, or Bonkers as he is known. My 3 year old Pedigree Tamworth goes out for £100 + the pick of the litter. He goes for 4-6 weeks to cover 2 cycles of the Sow.
Think about it in terms of costs, time & fuel.
Diesel for delivery of the boar. Collection afterwards. When the time comes, further time & fuel costs to collect your weaner.
My reasoning is that it’s best for the male to travel, and you to deliver. Would you let someone you don't really know, go off with your prize porker? For all you know he could end up on some ones plate! Lastly get the money on delivery.
As you can see from the above not a great deal of profit, but no loses either.
