I work for a small London-based company that specialises in helping corporate and private equity investors identify and evaluate acquisition and investment opportunities.
We work across all sectors and do undertake work in Eastern Europe from time to time. Unfortunately, I don't think we undertake enough work in these markets to be interested in forging an alliance with you.
However, we do have a need for specialists (i.e. linguists, industry experts and people familiar with certain markets eg, Eastern Europe) on a freelance basis from time to time.
Your background is clearly very relevant and so if you are potentially interested in freelance consulting opportunities in London then, in the first instance, please email me at email@example.com.
