a brief Google search revealed some offerings by the organization itself
Very interesting, though it seems the information is from Witnesses for Jesus, which is not identical to Jehovah's Witnesses.
I went to school (and made friends) with a "Witness", whose brother I gave some private English lessons. When my work before an exam was done, their mother came up to me and offered me a religious booklet, which I politely but not too enthusiastically accepted. Some time after that Jehovah's Witnesses actually turned up at my place, and hearing the voice on the intercom I was totally sure it was said lady. I refused to talk to them and afaik they never came back.
Said fellow student also started proselytizing (which he was probably expected to do) when he had reached the age of majority and once rang at another fellow student's door. Upon the smirking question, "Are you being serious, trying to convert ME?!?", the other fellow student was happily left in peace ever after. In conclusion, from experience, the Witnesses CAN be reasonable concerning the proselytizing "business".
BTW, does anyone know the British sitcom Black Books? The protagonist, trying to procrastinate his annual tax declaration, once asks two missionaries into the house. They are completely flabbergasted, stammer "This has never happened before!", but (or therefore) do not know what to talk about, show massive lack of elementary theological knowledge and are finally even taught biblical basics by the protagonist. Cracked me up!
