A few things that caught my attention:
On the Services page you have a small thumbnail image next to one step paint correction. I think we as detailers will know that the image is from a taped area showing before and after, but to the typical layman, they will probably not realize what that picture is.
I also think that your portfolio should show a split before & after as the first image after clicking on the thumbnail. I only say this because most people will just look at the initial image an not bother to click through the series. With a before and after, they can see the "before" and probably say to themselves "hey, that's what my car looks like" which might get them more interested in clicking through the series of images to see what outcome you can produce for their vehicle.
Just my 2 cents. Hope it helps.
