any one got any ideas of the cost of a engine rebuild....piston rings head block.etc .seems the engine has been cooked

Do you think anyone here is capable of doing such a job to a satisfactory standard

I share @petermik's skepticism  to a point. If it were me, and I was going to go down that route I'd consider that a dealership job. 

And as it happens, I was in a somewhat similar situation about fifteen years ago. The service manager recommended just putting in a short block rather than rebuild my old block. I thought he was jacking me around so I declined. Turns out he was correct since not long after some other stuff went south that would have been replaced if I went the short block route. Live and learn. Hopefully I'll not be in that situation again--good luck to you with yours. 

As an aside, mine was also a Ford, though an Expedition rather than a Fiesta.
