Damn dude, get some self esteem. I highly recommend you read the tech article entitled something like “F you, pay me.”.
1) contracts: You locates and produce the contract without their help at all? Google finders fees. Charge that at a minimum for the length of the contract. Get it in writing. What’re they gonna do? Take 90% of a multimillion dollar deal or 0%? “Hey, so I’m offering a multimillion dollar deal for a 10% finders fee for the length of the contract. You want it or should I go somewhere else?”.
2) They own the facility? Why do they need you specifically? JCHAO or CARF accreditation stuff? How much will they lose if they can’t get someone? What are their other options? Maybe they don’t need you at all. So you should take what they give. Maybe they’re desperate, so you should take what you can and get a stipend on top. Maybe they don’t have the cash, but they can do your billing for free. There’s tons of options.
3) Supervision is a REALLY gray area. What do they get from having students? Academic prestige they use to market the facility? They at minimum need to cover your malpractice and hourly fee. They think it’s free labor? Say 3 students, 15hrs week, charging $80/hr? Sounds like that’s $14k/month. What are they offering for that in top of your clinical work? And since we are putting this in writing via email, Mr CEO, surely you’re not suggesting that we replace paid labor with interns in violation of federal law, right? Now what do you think is a fair price of $14k/month? 60/40? So about an additional $100k on top of my salary?
