I would stay away from sending tells to strangers about guild recruitment. The /ooc suggestion is a good one. Either that or making a new toon and using /gu in Dalaya's Beginners *sparingly* (as in, mention it once an hour or something, not spamming every 2 minutes).
Sounds like a cool idea, though. Low level guilds have a lot more good options here than they did on live, with all the adepts. Good luck, and if you guys need any suggestions or help, the folks from Venerate would more than likely be happy to come to your aid. Especially if you spam Jose/Mythryn with tells (like spam spam... couple hundred lines of tells in 5 mins or so oughta do the trick). That'll get you on our good side quickly.
