Backpacking for 3 months in Asia early 2012...who wants to join me?

what is the best way to find like - minded & genuine fellow travellers to join me (a girl aged 28 with some travel experience) on a 3 months stint to Asia (Singapore, Thailand,vietnam, cambodia etc...) ? Im keen for a trip in the early months of 2012 and although I am capable of traveling by myself (as its always a great way to meet people) i dont like the structured approach of preorganised tours and do sometimes feel it is safer/more fun sharing the experience with others (even strangers!). Alot of my friends are either working, married or just not interested in the 'unknown'. SECONDLY and lastly...any good/helpful ideas on where to start planning a trip like this for eg. which country to visit first and a good route to follow! Thanks!
