I am working on compiling a comprehensive list of law firm practice
areas.  The list is composed of about 70 high-level legal practice
areas (listed below).  What I need help with are the sub-practice
areas within each top-level practice.

I need a researcher to visit 1-2 law firm websites (or any other law
related website dealing with the subject) that specialize in each
top-level practice area, and then compile a short list of the
sub-practices within that top level practice area.

Here is an Example:  

- Top Level Practice Area = "Admiralty And Maritime Law"
- Source = http://www.vanblk.com/practice/maritime.html
- sub level practice areas = 
Cargo Damage Defense
Slackage
Contamination
Property Damage General Average
Charter Parties and Bills of Lading
Arbitration Litigation
Collision
Hull and P & I Matters
Limitation of Liability 
Customs
Protests
Litigation
Fines
Seizures
Court of International Trade
Immigration
Marine Insurance
Policy Coverage
Defense of Claims 
Marine Liens
Maritime Pollution
Oil
Hazardous Waste 
Maritime Products Liability
Personal Injury Defense
Jones Act/Unseaworthiness
Products Liability
Longshore/Third Party Claims
LHWCA/State Compensation Limitation of Liability
Pilotage
Recreational Boating
Ship Repair
Negotiation
Bid Preparation
Protests
Terminal Operations
Intermodal Issues FMC Proceedings
Third Party Liability
Tariff Provisions
Tug and Tow
Casualties Agreements
Vessel Sales/Financing & Documentation
USCG Proceedings
Investigations
Hearings
License Proceedings

As you can see from the above example, the top level practice area was
Admiralty And Maritime Law.  The website I visited
(www.vanblk.com/practice/maritime.html) listed all sorts of issues
(sub practice areas) that Admiralty / Maritime lawyers deal with. 
This particular example has more sub-practice areas than most.  In
general, I have been able to find 10 to 25 sub-practice areas for each
top level practice area.   I need a researcher to complete this
process for each top level legal
practice area listed below.  And, of course, I need the research to
cite the appropriate source (website or websites) where the
information was obtained.

I have actually already compiled my own complete list.  I am posting
this question so that I can compare my results with someone elses to
see how much overlap there is.  I mostly used Google to build my list.
 The entire process took me a few hours (less than 5 minutes per top
level practice area), so I feel like I am pricing this question
fairly.  Please let me know if anything is unclear. And, thank you in
advance for your diligent research.

*NOTE:  I need this research completed by May 2, 2005.
