Personally, I don't really have an opinion as to whether you take on some cf marketing or not. What you could do, if you wished to conduct a marketing campaign, is set out what you would propose to do and how much budget you would need to do it, then detail the expected benefits and how you came to this conclusion. Having done that, the imms could essentially decide whether or not to contract you for this work.

That said, your post seems to overlook some really fundamental points, and left me with the general impression that whilst your management technique and experience might be valuable in the businesses you conduct in real life, they would be less so in the cf context.

For example, your pool of potential employees (whilst restricted to amateurs who know the game of cf), is not really an ideal match to the roles required by the immortal team. In real business, you have hiring and firing to help deal with this, and in most cases you have a significant enough volume of business that you don't have to worry about the applicant and customer being the same person. In cf, you do, because when you reject an applicant you risk losing the customer (i.e. player). Therefore there is an additional pressure to accept applicants, and you need some sort of process to further test the people that you take on.

I would also add that the arguments you put need to be able to stand on their own merits. I'm not sure that it is helpful to list your successes in real life to bolster your case. Personally, I could come up with a similar list, but I believe that the cf market/business model is completely different from almost any other that you find in real life, with the possible exception of a mutual or co-operative. Even they aren't expected to recruit exclusively from their customer base without paying anyone.
