Be aware that whatever you 'sanitize' the beans in will also contribute to the brew's flavor. I used bourbon to sanitize a bean on a batch. I used a bit more to rinse the jar the bean was in, adding only about 6oz total. You could REALLY taste the bourbon in the batch (5 gallons)...
Also, adding vanilla beans to the batch will do more to enhance other flavors. If you want to get actual vanilla flavor in the batch, you might need to use either more beans than makes sense, or you'll want to use something else. Age the batch on medium toast oak chips for 4-6 weeks, then let it bottle condition for another month or two, and you'll get vanilla flavors. I did with with just 3/4oz of chips (used boiling water to sanitize the chips before adding them to the brew). At <1.5 months you got the oak flavors. After two months, it transformed into vanilla. If you use more chips the time frame should be shortened. I pitched both the chips and the liquid in the jar (I boiled water in a tea pot, then poured enough to cover the chips into a sanitized jar, covered and let cool to a safe temp before pitching).
BTW, you need to give a thread more than 20 minutes before you start posting "anyone out there"... Eventually people will see it and post if they have ideas.
