I can't give all the details away here, but we need help building a system with Arduino and NFC. Happy to give a more detailed brief, please get in contact for more info. We'll pay up to $50 per hour for this, so do get in touch if you need some work.
Any one of those, I'm your guy. Pretty sure you aren't getting much response since you are so secretive that you won't even tell us what it is.... making an offer of paying "up to $50/hr" for what may be R&D and protyping for what is an unknown, well that's just silly.
