All the suggestions I read are better than this, but, if time and money are tight...
tilt bike onto side stand and block up the frame on opposite side. (tripod it, wheel, stand, block) If you have a garage and its practical, put a tie down on raised side of bike to prevent it going all the way over and tie side stand in down position (front lower engine mount to 'foot') remove whichever wheel your doing first. It can be a bit shakey but it works as long as your careful. Its a really good idea to have someone steady bike while you get wheel in and out but it should be quite happy to sit there as long as your not bumping into it. I have done this on my own a few couple of times, particularly 'on the road'
