IT or e-commerce sales coach

Is there any experienced IT services or e-commerce sales person available to give me a couple of hrs training on the optimum methods for sales prospecting for the IT industry?
I will have a telemarketing script prepared so it can be tweaked. I need someone to instruct me how to cope with gatekeepers and initiate a friendly conversation with decision-makers.
There is a short deadline, I would like to go live next Tuesday, so any training should be no later than following Monday.
