When I started out I had to do a number of price reduced or free details for family members, friends and co-workers and take a lot of photographs of before and a lot of after photographs as well. The work doesn't have to be free or even price reduced but the cars in the worst condition make for the most dramatic before and after photos and the guy who is content with driving a car that is severely neglected most likely won't be too thrilled about paying to have the paint corrected or the interior brought back to like new condition so a lot were done free.
There can be a lot of future value in the best photographs that you can take so if you think with a vision into the future (about the photos) then rather than these transformations being free details or paint corrections you should be looking at them as an investment in your company's future.
I would concentrate on stellar 50/50 photos and before and after photos. Below are a few links of some examples of some paint corrections that I had gotten a lot of mileage out of in the way gaining new clientele. Not only did I make a thread outlining the process, products and techniques with good photos but I also got glossy photo paper and printed the most stellar of the photos that I had gained from these jobs, placed them into clear document protectors and made up a 3 ring binder full of examples of my work that I could carry with me in my car or van at all times.
Here is one of the first details I did that gained me additional clientele through presenting the photos. It was not a free paint correction but compared to what I can now charge, it might as well have been free.

Here is another job I did where the photos, especially the 50/50 shot of the hood gained me a ton of future jobs. This job also was not free but today I know what my time and the transformation is worth. One day while searching the words "paint correction" in google images I found my 50/50 shot of this particular car in with the images that came up, so I know this photo has been viewed by an untold amount of viewers.

The link I am about to paste next was a co-workers car that was one of the best examples of neglect and hack work that I have ever seen. This thread and the photos gained from this paint correction, displayed to the right people with the right "rap" always convinces them that they need not look any further than me. When this transformation is displayed, I always get the job. I salivated over the before condition of this car and offered to do it for free just to get the photos because the owner would have never paid to have it done. Not only have I gotten a ton of work because of the photos of this car but the owner also refers me to anyone he knows who owns a car in similar condition as the before photos in this thread.

It is said that you must spend money to make money and this is true. Just the ink and glossy paper cost around $200 to print out all of the photos that I have in my 3 ring binder portfolio, not to mention the hours and products/supplies that it took to attain the photos. It is all investing in the future and has paid off 100 fold. Below are a few more photos that are in my portfolio that convince the viewer that I am much more than just a kid with a wash bucket and a can of wax.
They say that life is what you make it. This is so true and lots of hard work and some thinking and investing in the future goes a long way. If you build it and show it to everyone who has a car or special interest vehicle, you will get work.
Hope this helped you out. TD
