I agree with Old Glory that a weekly target should be set instead of a daily target. I don't believe, however, that cold calling in the field should be the sole means of prospecting if you want to get the rep ramped up quickly. At a certain point, he will need to follow-up via phone and email based on the data that he captures in the field, so time and activity targets need to be setup for these as well.
Something you could also do that would be huge for him is to sign up for a service that provides UCC filing data that can allow him to know when leases began on competitive equipment that has been installed in his territory. Using that, he can make more of a warm call to businesses about how things are with their current vendor & schedule contacts based on the assumption that leases were signed for 36 months. Some leasing companies also have tools that can be used at little to no cost and provide company information such as executive-level contacts and contact information (including direct #'s and email addresses) to allow him to understand the businesses he is contacting.
Lastly, take a look at your existing client base to understand what size companies in particular vertical markets you have the greatest chance of success in, & have him make gaining entry into similar businesses a priority. Educate him on WHY you have experienced success in these client accounts as well as the business value that your company means to them. This will help him develop a solid talk track & give him a focused approach that he can yield better results than a shotgun approach.
