If you still need a long-term seller, please consider me. My nation is 50 days old, and I am in the process of completing two tech trades. If needed, I can still send you the tech before you send the money; but doing so would either risk tangling up my rotation or would push our trading cycle back about 10 days.
Here's a link to my nation:
