I have used Freightquote.com, bad job. I tried uship too but they have scammers (
one of them is a referral of cudachick)
I actually did a search online and if you search for freight classes (like I did) you will find a couple of companies. I used
Freight88.com (great rates) and
Freightshippingcenter.com (good rates, poor service),
freightcenter.com (tried them first, bad service and bad rates)
