You will not an expert after training. It will take years of working in the industry to become an expert.
Consider training like being on your "L" plates learning to drive a car. After training, you will have your "P" plates.
After training, your first jobs may even be your own home, friends or family etc, working by yourself. Your first paying customer job would be a small domestic job. Small drive / path / patio etc. In the $1,000 to $3,000 price range.
As you gain more work and business confidence and possibly staff? you then have the choice to expand into larger jobs, up to the $10,000 + price range with Retail, Commercial, Government etc.
That's where the Head Office support systems are so important. Including:-
1) Operators manual covering over 50 topics.
2) Access to our Licensees Secrets
3) Contact details of all trainers (with real job-life experience) for 24/7 communication.
With emails, photos and talking over phones, even on-site support. There is nothing over the past 25+ years we haven't been able to help Licensees with.So over the following months and years, the more jobs you complete, the more experienced you will become, the more of an expert in this industry or professional racing car driver you will become.
