Flaws in Business Plans of Remote IT Department?

Anonymous Tech Support asks: "I work for a small technical support company that is hired by local companies to manage networks, fix computers, and be the IT department in general. Last week I was working on a small network of 25+ computers. After a week of emotion and annoyances (long story), I have to ask the Slashdot community: How many of you are employees of small 'outsourced IT departments?' How much does your company charge per hour and how much do you make per hour? What sort of agreements do you have with your employer (non-compete etc.)?" The company charges $65 per hour to regular clients and I make very little of that. It seems like the business model is faulty, pushing us low-level yet skilled employees to start a company and go-it alone. It also seems like outsourced IT departments cannot have employees that will not leave or be disgruntled unless they are either a) paid enough or b) given a stake in the company. Do any of you have experience in this? What sort of business models exist out there for the remote IT department?"
