If you really have a 75% conversion rate once you start talking to people that is outstanding. Next you should validate your intuition that spending relatively modest amounts of money on adwords will double or triple your flow of customer leads. If that hypothesis holds up under real world testing then you have a business and need to transition as quickly as possible! Even if that means taking on an investor. In most b2b environments I have been exposed to a 1 to 3 week wait time is not a deal killer if you have something they want/need. I think I might deal with customers in the wait time transparently. I would tell them something like the following. We are growing like crazy and our backlog for setting up and training new customers is about 2 to 3 weeks. Please be patient with us. We believe each new customer needs some personal attention up front to make everything go smoothly and ensure that we are set up to serve you well over the longer term. Obviously we won't start billing you until you are completely set up. If for some reason it takes longer than 3 weeks to get you set up we will give you a free month of service at the end of your first year.
