Hello,
Engineer here on this side.
I have done CDR for Engineers Australia myself and my partner is a computer engineer too.
I know what it takes to write a successful CDR. Don't be fooled by other bids, who will treat this as a writing project. I have got a successfull EA recognition.
For 100 USD I can also give you my CDR report which you can use as a template to write your own CDR.
Let me know what works out for you.
Regards,
Debayan
