Hi Kuana: All the responses to your questions were good advice. The people on this forum know what they are talking about.
You must know that the company your are going to work for provides top-notch, professional service. If you don't believe in the quality of service you are selling you are wasting your valuable time.
If the owner of this company is genuinely committed to providing a valuable service he will have no problem letting you talk with the technicians, watching them work, and he should also provide you with testimonials from past customers. He should at least let you speak with some. If he hedges on this I would advise you to forget working with this owner. You will only damage your personal reputation by selling a 'shoddy' service.
But if the technicians are dedicated to providing quality repairs, and the owner is concerned with providing great customer service, you have an excellent product to market. One you can believe in. And windshield repair is a huge market with plenty of opportunity. It's competitive, but what isn't nowdays?
You're going to have to do some 'grunt' work to get this going. In other words, you will have to physically call on new car dealerships, used car lots, and auto insurance companies in person. You should work out a 'deal' with the owner that allows you to offer a FREE windshield repair to the large dealerships, to show the quality of your technicians work. By giving one FREE repair (at the owner's expense) you could secure an on-going account that would provide both you and the owner a steady stream of repeat business. And business people don't normally turn down anything 'FREE.'
I have a saying that worked for me as a young salesperson and I advise you to follow it..."put your belly-button directly in front of 20 other belly-buttons per day." Tell them about the benefits of your product/service, not the features. Show them how it will benefit their personal business (not yours) to use your product/service. If you 'belly-button' enough people you will find success. Make those 20 sales calls, not 19, per day and you will get business.
Hope this works out for you Kuana. If not, you can email me at coachdoug60@comcast.net and I would be happy to help you find a product/service you would enjoy marketing...
