Thanks for your response Magnus. Unfortunately I have not had any luck yet.
I grew up in Dubai, my own experiences show that IT vendors out here generally are not attuned to catering for enterprise needs - when compared to the way in which international firms cater to the enterprise. I am yet to come across an extremely competent vendor for any type of hardware or software service (our Oracle Financials implementor was not very good!) - perhaps it's a reflection of our business being and SMB rather than a larger corporate, however I think that the level of IT services in general is pretty poor!
Looking for an implementer for OS X that will meet our requirements seems to be a pipe dream! I am considering going at it on our own, however the biggest issue seems to be end user support, that would be difficult to provide in-house, cost effectively. The other problems are data migration (which can actually be handled with a little legwork) and user training, i.e. moving from a Windows based platform to OS X.
It may even be an idea to eventually spin off into a competent OS X based enterprise implementer..
If anyone has any thoughts, recommendations or general advice, please do let me know!

Omar Kassim
