Great dude - that book is the bible of sales, my teams and I gave billed millions in sales across various companies and job functions I have worked for over the years, I would swear by it. Even though now I have adopted and customised various elements the foundation has remained constant. Glad your MD has a copy too
Dude selling outsourcing, monitoring services or helpdesk is very difficult to IT managers, your target group is wrong. You might as well tell them you are selling them something that will help reduce their team and may even threaten their own job security. For these services you need to target FD's, Group Financial controllers and MD's/CEO's - i.e. people who have a remit to reduce costs - these guys are usually 'gatekeepered' but once you get through and deliver your message the rewards are much better, you dont have to then deal with budget allocation (since you will be talking to budget holders) and your target group will be much more defined and more importantly relevent.
Im not saying disregard IT managers completely - hardware and anything that generally makes their job easier is of interest.
BTW sounds like you have got through to some people and engaged - well done!
keep us posted!
