There are several components to a data recovery company.
1. Tools. I think BlackST posted a list in the past. PC3000 UDMA + DE = $15000, PC3000 SCSI (if you are working with SCSI RAIDs where more than one drive failed) + DE = $15000, microscope, oscilloscope, clean room equipment, imaging equipment, rework stations - it adds up...I have to buy it in pieces as we are getting more and more clients.
2. Parts. You need to stock PCBs, donor drives, and lots of them. This only comes from high volume of work. You also need to know parts compatibility and that information, while available, is scarce and very distributed.
3. Staff. You need someone with both EE and CS background who can understand various file systems. Ability to program embedded systems is a plus. That person should ideally have ability to read research in Russian and Chinese. Can you hire someone who is an equivalent of a multilingual neurosurgeon for less than 6 figures for that role? I doubt it.

4. Training and R&D. It never ever ends. You'll spend several thousand dollars on training and airfare alone, which will get you basics. Then you have to keep up with all the research as manufacturers continually make our lives more complicated. This is quite literally a "black art" that relies heavily on reverse engineering. Vendors eventually integrate solutions into their tools, but there is often a period of exclusivity when only a few people in the world can solve the problem. That, my friend, is what you are paying for when you refer to our rates. As you know, in every IT company a ton of unbillable time is spent on R&D and training. What happens when your staff realizes he can quit and compete with you for a lot more money?
I didn't even mention marketing.
In summary, unless you think you will do more than let's say $120,000 worth of work per year, it may not be the best suggestion to setup an internal data recovery company. My recommendation would be for you to concentrate on your core business and let us concentrate on ours.
We are in Silicon Valley, so let's chat sometime. I think you'll like our proposal. We offer not just data recovery, but also post-recovery data reintegration (Exchange, domain controllers, SQL, Linux stuff etc). You can consider this posting biased, but it's the truth.
