I think he wants an honest opinion of how much the club is worth from someone out side of SISU. Hoffman could give his boss a decent appraisal of how much his boss should part with and would also be able to give him a pretty good idea of what total would prize CCFC from SISU's hands.
If he goes straight to SISU, they will, like the money grubbing bastards they are, try to take him for all he's worth etc.
Once he knows both sides of the story (aka what Hoffman believes is a good amount and what SISU believe is a good amount) he can consider how much he's willing to part with in order to gain total control of not only the club but also the stadium and all its holdings etc.
It's commen business management to seek outside opinions first before going straight to the source!
It's really not too difficult.
First step is to find out if sisu want out ... only sisu can tell him that.
Second step is to valuate the club and it's assets and liabilities (due dilligence).
Third step is negotiate a realistic price for the loans and acceptable payback conditions.
Fourth step is to write the checque.
Nothing in there calls for Hoffmans 'expertise' - just simple accountants, financial advisors and a few lawyers.
It will probably take 6-9 months without Hoffman ... 18-24 months (and a higher final payment) with Hoffman.
