One of the ways of attracting investment
which is not yet sounded, especially convenient when working with foreign investors, are the special "investment boutiques" who act as intermediaries.

In addition, they are able to do if not themselves, then at least explain how you need to prepare documentation, plan, investment Memorandum and other papers in order to liked to the investor.

It is also necessary to consider that they work more with investment funds, not private investors, and these relationships have their own specifics. However, a link to one of them (Beford Investments) I threw, see if You can help.
