Alfresco professional for Mac OSX

We're looking for an Alfresco professional who can install Alfresco and set up basic configuration like SMB/CIFS-shares over VPN, OD-authentication, etc. This has to be done on a Mac OSX Snow Leopard Server edition system and maybe also on a CentOS Linux server. Please let me know: how much experience do you have, what time it will take to do this installation and configuration. Mention the word 'banana' in your reply, so I can see that you've gone through this description.
