Don't let my higher than average bid scare you off. I do this type of work a lot, so I have a lot of infrastructure available which makes it easier to complete the work. I do all the work on high-power servers in a US data center with high speed redundant internet access, so moving around large files / file sets won't take days.
Unless the image is encrypted or running some strange file system, it should be no issue to mount up. I work with Ext2/3/4, Reiser, NTFS, vfat, XFS file systems in raw, vmware, iso, and a few other image formats.
I can provide you with an NDA for us to sign, if you wish to confirm data privacy.
Once I have the image, I'll know if I can complete the work within a couple of hours (ie: if the image is mountable/readable, etc).
I have a lot of low-level experience -- I don't rely on fancy applications to the work for me, so if there are issues mounting the image and/or reading files (ie: corrupt file system, etc), I have plenty of knowledge and experience dealing with it.
