My problem has nothing to do with fear of my credit card number being swiped. Heck, i email the number all the time, I'm not worried about it. It's just the perception I have of businesses with no land line, cell phone based credit card processing, homemade paper business cards, VistaPrint magnetics, most any business with LLC at the end of their name and salespeople who pull up in $60,000 pickups. I'm just not trusting their work to be in my best interest.
I know, it's judgemental as hell and admittedly there are always exceptions but anything that gives me the impression a person is only minimally invested in their business just screams to me that they're going to shut it down and disappear as soon as things get a little rocky and won't be there to stand behind their previous work.
Again, that's just me and I know there are exceptions.
