Hello,
I am a Firmware developer and have quite a lot of experience with openwrt. I can help you with this project but since you need the actual hardware modification you might need send the hardware to me or I might show you how to do this and you can get it done locally. And for the OpenWrt firmware part I will guide you to build the firmware locally. If you are interested in giving this project to me I am going to need to know which hardware platform are you going to use? If the router that you use is commonly available like tplink or others I can buy it here and show you how to do it.
Awaiting your response.
Thanks
P.S: I dont understand why people have bid ourtageously high on this project, do they even know the technicality of this project?
