I am kind of new to the industry(about 7 monthes). I have been doing contract work for a small company doing mostly vinyl graphic removals off of tractors and trailers. This company is starting to turn down removal jobs unless they are also applying new graphics after. Therefore, my workload has diminished tremendously. I was wondering, 1. Is there a market for a company doing removals only? 2. What all would I need to do legally(what kind of insurance?, do i need a business license etc.)? 3. How do I price the work? I'm guess you base the work on the estimated number of hours and multiply by a certain rate what is a good starting point, or a range to base the hourly rate. 4. What kind of paperwork would I need to establish for the jobs and any liability statements that should be included? 5. What is the best approach for securing new business? Another question, Do most graphics companies do thier own removals, or, is there are market for a removal company to contract work from the companies that are applying new graphics? Hopefully, this subject matter is acceptable here. If so, please provide any advice/suggestions/input you could offer. If the material is out of place with this forum; I truly apologize. Any help or the suggestion starting point to find these answers would be greatly appreciated. Best Regards, Dirty D - Atlanta, Ga.
