For every 3 meetings with prospects, you should expect to make 1 new client. Thereafter, you should start asking for references. For every 2 reference you receive, you should expect to make 1 new client. Thereafter, once clients start referring new prospects on their own, you can expect to make all such references as your clients. Doing the math, if you meet around 600 prospects, you should be able to make 200 clients.
