It sounds like you want Acting, Protocol, Negotiation, and Streetwise as a baseline. Do you have Excel? If not, I can copy and paste from my spreadsheet into text here...
for attributes I would say that you would definitely want int and cha up there with CHA as essentially your "main stat"
the question is do you want to try to stack the traits that will improve the char (but make them more of a 1 trick ) or not, because I would look at attractive and gregarious.
so steiner
primary language German,
secondary languages, English, Italian, scots Gaelic, Swedish
you will want to look at the affiliation info on pg56 ATOW
any of the provinces would work, but they all have slightly different effects.
pg 65, 66 pick an early childhood if using modules
then continue working through. although point buy may be easier, going through the modules builds a more rounded char IMO and helps come up with background hooks.
modules end on pg 81
if you want to be a MechWarrior you want the MechWarrior field skills at some point
you might also look at the character archetypes pg 94-101 ish for inspiration
traits start on 107 more or less
for a social focused character gregarious and attractive would help, but may not totally fit the concept.
