Man, you read my mind. There is a big difference in high touch personal service and routine run-of-the-mill operations of large corporations. Just an observation. To my clients, their stress is my problem; regardless of who failed to do what. Welcome to entrepreneurship; you eat what you kill
Let me clarify.... This is not being crass, but merely pointing out that many clients love being in contact with someone who actually knows what they're doing and not giving them a lot of run around. We have many 'heavy-hitters' here who I'm sure provide the highest level of expertise and service. It's a combined passion of what you do and providing reliable services for a fee. It's a different game from the 9 to 5 when you're starting your own practice.
Good Luck
Yes, but. Being a high touch and responsible service provider is one thing. Taking on business you have no business taking on is another. Most businesses fail because, well, at least in part because they don't say no to business that 1) they can't serve (because of expertise, capacity, and the like); 2) the client WILL NEVER BE SATISFIED no matter how much you do for them; and 3) client's that "retaliate" by being slow pays or no pays when they just don't like what you are telling them.
A lot of that is hard to tell up front - BUT, having a plan to avoid them is better than not having a plan.
