What do I need to look at when it comes to moving a doublewide?

[Eric F.]

A lady called me with a doublewide she wants to sell once her house is done being built. I looked at the home and it is in excellent shape. However, I am not sure what I need to do to see about moving it. I looked under the home and did not see axels on it, and it did not have tongues to hitch up to the mover either. How much is it to get those put on to move it. 

I have never moved one before and would like some guidance. I just assumed it costs 5k all in but that is based on no experience.  Has anyone moved one? How much effort and cost was it?

I would be moving it to a park.
