Breathig Excersise Animation

Looking to create short animation to illustrate yogic breathing exercises. I envision semi-transparent yogi sitting in the lotus posture. - on the count of ten (ten seconds) yogi breaths in, in the middle of his head blue sphere appears, color intensifies - on the count of ten yogi is still while holding the breath and that blue sphere is at the peak of intensity - on the count of ten yogi exhales, blue color is gradually transferred from sphere to the entire head and neck - on the count of ten yogi is still while holding the breath blue head and neck are at the peak of color intensity Above is the description of one exercise, this project is for 3 (the other two are similar, I will explain it to qualified bidder). There is no preferences of what technology should be used to create the animation except that it should be web-friendly as video will be posted to the web site. Please provide me with some examples when you submit your bids to help me decide what fits my needs the best way. Thank you
