Answer 1

There are companies that do that sort of thing. They have grappling hooks and pipe grapples to retrieve objects from boreholes.

I would start in the yellow pages under "well services" -- even "well drilling" -- to find a company or person who has the proper equipment. One of these guys listed in the yellow pages should be able to tell you who can grapple your pump out of the hole.

Answer 2

If riser pipe in intack, or chain / rope, & if no check valve on pump, then backwash thru riser pipe.
If check valve on pump, try small long continuous air hose or water hose to jet out mud around pump while puling on pump.
Or, if you can fill well casing to top, you can vacuum thru riser pipe, or long hose.
