I think you need to find a local consultant. Someone here might have a
suggestion or two where to look (as I do below), but this list only
provides help on R programming code, not statistical issues (see
programming guide below for details).

You might wish to have a look at the CRAN survival analysis task view
to see if any packages might address your needs (but warning: it's
mostly about medical applications):
