We are in the service industry, that is foremost. It starts with being professional about all aspects and details of the task at hand. You can be a "pro" with a set of EONS and one mic, if thats what the gig calls for, or a full blown v-dosc system. It's all about implementation, performance and in the end, meeting/exceeding the customer's needs ( a bit of corporate speak there ) Its not all about the gear, its about relationships with people, and providing what is required.
Of course, experience, the appropriate/good gear, and talent are all required to be successful.
Some may say that a part timer like myself (ankle biter, weekend warrior, what-have-you) may not be pro, I don't have a warehouse, a diesel box truck, or an accountant, but for the limited business I do, I provide a professional product, high quality service. I know (not being egotistical) I am as good as or better than, and am competitive with "pro" providers.
