I code for free around here, but I don't do software updates/reflashes. I can definitely help you get your machine set up if you run into issues, but the DIY is pretty straightforward. Only notes I'd add to it are that if you use a USB cable (the DIY was written with an OBD to serial cable), make sure you set it to COM1 and then go into the driver properties > Advanced and set the Latency to 1 rather than 16.
