I took a stab at Joe's RAW file and this was my result.
On the left is the result I got from RAW Shooter Essentials (only my second image with this program).
In the middle was the result from DPP using the Linear Tone option.
On the Right was from DPP using custom Tone settings.

Each of these I tried to make the image look the best as I could and did some editing in PS.
