I think most of the OP's mods can be ordered online; prices can be seen at the sellers' website.
Ti bottom bracket:
Ti Sealed Bottom Bracket (Japan Bearing) | Bike48 - Brompton Ti Custom Parts
Bikefun rear suspension: http://www.bikegang.co.uk/#!store/c7qz
Etc.
Not sure if OP did his own installs/swaps. NY labor prices would be more than those in the Philippines.
