Google Analytics Expert Required

I have a client that requires a very detailed Google Analytics setup. I will manage the setup on their account, but I require some assistance and consultancy on how to best setup the account initially to handle multiple domains/sites, and also how to manage custom variables. I'd prefer to work on an hourly basis with a cap the spend, so that I can choose which areas I get your assistance with when the time comes. I need some assistance now to plan the setup for the client's suite of sites, then on an ongoing basis for specific sites as required.
