If you are flying from Denver, are you looking to fly internal routes only? If so, I guess there wouldn't be much demand for general cargo as it would be more cost effective to truck internally.
As for operating from the UK, you're better off going to one of the 'regional' airports, for example EMA or STN.
Not sure how you'll get on hopping an A310 all the way to the Far East and back!!! There is so much capacity out of Europe to the Far East, current operators are almost flying cargo for free!
Good luck with the paper.
