When everyone has access to the same tools then having a tool isn’t much of an advantage.
Hmm, I have the same tennis racquet as Novak Djokovic...
When it comes to photography, (and I guess also home renovations), having the same tools as the pros just means it's easier to make better quality mistakes.
Nevertheless, in the eyes of a customer, all photographers look the same because we all use the same tools. So how does a customer decide with whom to do business?
By attitude.
"Attitude" doesn't just mean the tone of the person's voice or the words they use in an e-mail. It's the appearance and flow of their web site, the "feeling" of their pictures, the depth of their expertise, how quickly they respond to e-mails, how they dress for a job, how they deliver the finished pictures, etc.
A professional attitude is just the start. You also need a personable attitude, ethical attitude and of course everyone's favourite, a positive attitude.
