Speaking as a Ford trained qualified panel beater who cut his teeth on this model, i would advise against. Even in the UK with readily available parts, it would not really be viable.
With front end damage that severe, you will need a body jig to realign the chassis - failure to do this will result in poor roadholding, poor steering and advance tyre wear at best.
As for parts, you will need fliches, possible chassis legs, engine parts, mounts, front crossmember, slam panels, front panels plus all the obvious bits you can see - really never worth £3000
Come back for a holiday and see what you can find over here of similar strain. There will be plenty on the road for that sort of amount - or even visit an auction! Paying at auction for a van of that age will not cost very much at all - and will pay off in the long run!
You also have the advantage of being able to buy something with short mot, as you are exporting anyway! Better to weld a few plates on a chassis than rebuild a truck from scratch!
