Is there a specific research/business guide for Egypt?
I’m not aware of a research/business guide but perhaps try The Egyptian-British Chamber of Commerce. I’m sure they would be able to advise you and perhaps help you make contacts.
Here is their website – http://www.theebcc.com/
If you get to a stage where you need to ship goods to Egypt you can apply online for the required documentation for origin and preferential trade at www.e-zcert.com/uk
