If the goal is to cheaply handle crappy lawsuits, you need to maximize volume while minimizing costs. You might have a business development effort in San Francisco, but the actual work can easily be done from an office in Omaha. You don't need smart, idealistic Berkeley grads to churn through meritless suits. $35k + benefits is a very good salary in Omaha and will attract perfectly competent people ($35k would attract only desparate people in San Francisco). They won't have much experience, but you can amortize the cost of a good training program over a large volume of work.

Much of your value add is going to be in streamlining the process: developing tools and processes to minimize the time it takes to handle a particular suit, and aggregating knowledge about particular patents and particular trolls to amortize the cost of dealing with them over multiple clients. At the end of the day you need a licensed lawyer to sign off on any filings, but everything else can be automated.
