Bavauto.com has OEM and aftermarket parts up to you. Purchased a lot there without issues. You probably will need both:
Outer door handle carrier - part# 51 21 8 243 615 (driver side)
Outer door handle - part # 51 21 8 243 617 (driver side). If they dont have the correct black color for your ride you can purchase unpainted and have it painted at bodyshop. Done it before on my gray 4.4

Hope you can get in. Good luck.
