Hi Waterbourn,
there are two reasons why no one want to process your data. The first is, that you do not have much posts, so the probability that you react to an answer is low. The second reason is that your flats are not very good. There are much dust and a color-vignetting left in your image. I think this is the toughest thing in your data.
Nevertheless I had a try. It is far from what is possible, but maybe a little bit better than your try.
My workflow is not much different than yours, but with some other adjustments.
If you want to, you can download my processing icons here:

For the "color boost" processes I have used a luminance-mask of your image. For the "reduceBackgroundcolor" process I used the same, but with inverted mask. If you do not know how this works, tell me.
If you want, you can download a 16bit-tif Version of my try here:
