The tilt-a-rack should work well. I would contact a couple of welding companies and then go visit them. If they can do the work, find out if you must make an appointment and what time works well with them. You do not want to show up with a 30' trailer and them not be ready for you, with no quoted price.
If you go in and find out their labor rates, find out if you need to buy something or not, perhaps they need to order a hitch extension to weld to the cross pieces that they have on the shelf.
Good luck,
Fred.
Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
