I understand that the uncertainty with the Trace Instrument's project is causing some scheduling nightmares. I want to briefly update you.
The project smaller than we first thought. Initially it seemed like a cast of thousands would be involved. However, the company will pay for only three of us. Steve, Ming, and Stacy will work on the project. While you may be disappointed, I'm sure some "cost overruns" by the team will teach Trace Instruments a lesson
I have your name and will contract you if the project grows.
