TotoLink a3002ur V3 add support

This is what a 6 year old sounds like trying to understand adults - I'm new to all of this, and request some great minds kindly come to my aid for creating an OpenWrt build(?) for this missing router. I started a small business and would like to give customers wifi access as needed. I want to learn and find out how I can contribute to this amazing community, and I WILL get there, but right now I don't have the knowledge, just the router. I follow instructions quite well, and I am intelligent enough to understand most of the ones I have here read thus far (and I do realise routers are temperamental and I still might brick it, but I reckon I'll have a go at installing it, following the instructions to the letter). Thanks all
