No offense, but it is starting to sound more like you're trying to find people to do work for you rather than find help solving some unique problem.  There are several websites containing Stata tutorials and also a book on data management and workflow design from StataPress.  Additionally, if you've read through some of the help files for the commands you are working with you would likely find substantive guidance that could help you solve your problem.  The other option is to hire a consultant to program what you need and work through teaching you how the code works to solve that specific problem (even though it might cost a little you kill two birds with one stone this way).  

What have you tried thus far that has failed to yield the results you are looking for?  Can you replicate the problems with other datasets so other people can work through your exact problem?  The Statalist FAQ has a lot of good information that could help you construct a question that would get the answer you are looking for while also ensuring other people with the same problem in the future could find an answer quickly/easily by searching through the Statalist archives.

HTH,
