While I am not sure of the specifics of each patient's treatment plan, I am sure it will cost approximately $125 for a 55 minute session.... so based upon that, I would schedule each person to begin with at 2 visits per week, which is $250 each per week, or $750 per week for all three, and that is $3k per month, or $36K per year, with only 3 patients, and that seems like a real nice start. And that leaves, in a 4 day work week, from 10am to 5pm room for 29 more 55 minute sessions, which would work out to apprx, $210,000 per year if you value your sessions at $125 each, and work steady 7 hour days 4 days per week, 52 weeks per year.
So, given the above, it looks like a profitable venture. And you could also supplement all of this with group sessions at a reduced rate, maybe in the evenings, 1-2xs/wk, you could create reading matter to sell, motivational CDs specific to your area, do group Webinars, where the patients log in from the safety and anonimity of their own homes...
Just a few ideas...
