What I've seemed to notice around our small town is that there used to be lots of businesses out there, some were hacks, some knew there stuff. Seems like lately...most of the hacks didn't survive the "economic stuff" and all that's left are the good guys. Since they're good, they are in high demand, and they can choose what jobs they want.
I've tried to get a quote on a bathroom remodel twice in the last two months. Both guys said they'd come in a week or so, that was a couple months ago. It is what it is. I'm almost the same way at times. I'm so busy, that unless you are an existing customer, you are gonna get pushed way back. If I can judge the customer is hard to deal with via email, phone, or in person, I won't even give them a time table, I'll just tell them I don't have time and send them elsewhere.
The good guys that do return calls, are all miserable working 80 hours a week, and hate their lives. That's just around here what I've noticed from talking to small businesses...I guess I'd think that going to a corporate world (like most printer company's) would be getting back with you.
