I want to answer your asked fair questions, in advance to be anxious isn't present the basis. The signing party pursue the mercenary aims on others finance. Your first scheme on 104 BI is clear to me and my partners and it has to be signed with you on 200 BI.
Your scheme is painted, true. I completely support you. To intermediaries it is necessary to pay attention only at the final stage, to stages of signing of the contract which will provide them 2,5% of the contract sum what I don't doubt. It isn't desirable to accept councils from outside, I advise to sign дравт - the contract only on your conditions.
