TM,
I hear you - it is hard on those of us that like being around people, especially "our own."
I will warn you that, IMHO, I would suggest that you "sieve" out the potential bad karma by agreeing that the office expenses be paid by both (all) parties for a year in advance. I would also recommend that you agree that only trading business be carried out there...
Hope for the best to you finding that key aspect of the trading puzzle...
