I've been receiving requests for master quests from both my clans and also clans that don't have an active Watcher right now, which is fine with me, as I love writing these. However, please be aware that as of today I have 5 on my desk, and the wait time is approximately 30 days give or take from when I mail you back. I am writing them in the order received, and January has me on business travel for almost half of the month.
Let me stress this point: I am not worried about writing these quests, and they actually feed my creative process, so don't be worried about mailing me. Just be aware that your master quest will not be an immediate thing, but they will be well worth the two hours of your play time when ready.
