I've just started in the ADC field. I think I am the only one in my area so it's not like I am in direct competition with anyone.
But even If I were, there are those times when professionals seek the advice and help of other professionals. In this way we can better serve our own clients.
For years I have made my living as a plumber. I do plumbing repair and light construction. I'm not in competition with the other plumbers in my area as much as we are working together. We keep in touch and discuss new techniques and code changes as well as new materials on the market. We also talk about problems we've encountered and what ways there are to solve them. Then, on occasions, we may discuss problem customers who can be either hard to get along with or bad about paying their bill. This is good, helpful, need to know information!
Then there is this as well. Some of us are better at one aspect while others handle the other side better. We can learn from each other or even trade off jobs. Also, there are those occasions where I may have to refer one of my customers to someone else because I can't get there quick enough for one reason or other. Just as I've had other plumbers refer business to me.
I've even been called on to help with someone else's job because they needed my knowledge or equipment that I had.
So, in reality, real professionals communicate all the time with one another. It is in this manner that we ALL can provide better services at reasonable prices.
Or.... I could just give you the short answer. "Hey! I looked at your foot! YOU OWE ME!"
