How can I raise money?

If it is nothing of value, like you say, tell him to donate it all. Otherwise, drive over, pick it up and drive it all back so South Dakota. USPS, UPS, etc. will cost you big time. I just sent a small box today by USPS that weighed no more than 2 lbs. It was about 2" x 6" x 10" and it cost me almost $25 to ship. A flat box rate was not quite right. It was going a bit farther than your distance but, a room full of stuff is not going to fit into that size box or any one box. I ship all the time on eBay and a box of about 38" x 12" x 12" is going to cost you about $50. It is not worth it unless your items are valuable. How you raise money is a problem because if you get a job, you obviously cannot leave to pick up your items. You should have taken your things with you when you moved.

It may be much cheaper for your father to ship you your stuff via UPS.
