You are fighting an impossible cause. We aren't designed to know and care about this many people. If you intend to let your business grow beyond 10 individuals (Yes! Ten. Those people each have at least 3 people they care about, making the minimum count 30 already) then you will fail to accomplish what you are looking for. More importantly, if some of them fall for it and begin to trust others at the office, they run the risk of being *deceived by someone they are attempting to trust*, while at work. You will have effectively attached their desire to work there to the outcome of any one relationship they build at work. If *one* relationship goes sour, the person is that more likely to leave altogether. This is why you want all relationships to "not mean anything" at work. It's important to the business.
Other than that, best of luck.
