Charley,
Unless you break it up into several boxes, you are beyond UPS ground weight limits, and I found that UPS freight is not competitive on the several things I got quotes on.
Normal freight is probably the best option. You can use freightquote.com or any of the other internet-based services -- I have not used them myself. They will get a bit of profit, but they will help you with a lot of little details that can be a pain to figure out. I have heard both good and bad about these services.
I have had several very good experiences sending and receiving freight, but there are gotcha's. If you have pickup or delivery to a residence the additional fee is $50 to $100 or more. On the other hand, I once got a delivery for free because "the truck is coming your way anyhow. I strongly recommend putting the article on a pallet, covering it with plastic, and strapping it down yourself (or an individual acting in your behalf). A crate on a pallet is a more expensive, but more secure option. Then deliver it to a freight company terminal yourself (or your agent). Then pick it up yourself at a freight terminal (of the same company, if possible). I am lucky quite a few major companies have terminals near me where two interstates cross.
It used to be that freight companies absolutely did not want to deal with a non-business amateur at all. In the last few years some companies have decided that it is in their interest to work with individuals. YRT & Roadway have been quite co-operative locally, but I cannot say that they will be that way everywhere. I assume you are at the receiving end -- it is probably best to make arrangements in person at the sending end. If you can get someone to act as your agent to do this you can avoid misunderstandings. I once had a buyer arrange for freight because he had a business relationship with a company at his end. He made the arrangements and sent me a copy of the pre-paid way-bill. I took the way-bill & the pallet to the freight terminal and dropped it off -- no fuss at all.
The main advice I can give you is to "do your homework" -- if you know what the freight company expects, they will work with you. There are a lot of "gut feel" things like finding out what time they are least busy so that they will be more interested in working with you. I cannot do this for you and every case will be a bit different.
Do some investigating about what freight terminals are near the two ends of your freight's journey. Using one company only and avoiding any extra handling for pickup & delivery has always worked best for me.
Feel free to ask some questions in this thread after you do a little research on this project,
Archie
P.S.: One of the things you will need to deal with is the archaic way the freight industry tries compensate for the weight to volume ratios of different things. The more experience I have with this, the less I understand. My bottom line is that if you get something reasonable (even if erroneous) the freight will go through. This is almost certain to work out if you can connect with one person at the freight company that will help you.
Remember -- I am NOT an expert. I would be happy for someone that is to add to this thread, even if it contradicts what I have experienced.
