I get the paranoia too and trying to do what I can to let you know who I am, where I live, where my business is and so on.
If you have other ideas as to what will make people feel more comfortable, let me know.
So far I'm meeting people in my apartment/office in SF, giving you my name, address of my factory in China and you can find lots of information about me including videos and probably articles when searching for my name.

You can also find all my personal information which is registered publicly as a director of Nemo power tools (you can search the HK registery for free).
Short of providing my birth certificate, I'm not sure what else I can do to to convince you I am who I say I am.

In any case, all of this doesn't guarantee anything, but it does mean you can sue my company or me personally in case you pay for the group order and don't get the units or your money back.

We conduct business with hundreds of companies and individuals in Nemopowertools and have dealers in over 30 countries. If you feel unsafe, do some research, look over the dealer list on our site, contact our customers, read reviews, come meet me in SF or call me on Skype.

It's getting a bit frustrating to have to address this issue over and over again. I'm far from anonymous at this point.
