Cleaning a sensor isn't that hard to do. ; Most of the time all I need to do is use a blower but I have done the sweeps, too. I blogged about it here:

I read your sensor cleaning blog and I must say, YIKES! The one thing I would NOT do is use a cleaning solution. I know they sell these kits, but again YIKES! I used to sell cameras. OK it was back in the stone-age when Nikon F1, Canon F-1, & Olympus OM2's were kings fighting it out for dominance. Even back then we sold lens cleaning kits with solutions. We did because many consumers wanted them. We recommended not using them unless something would not come off with a soft lens cleaning cloth.
Most people made a bigger mess than they had when they came in. I see lens cleaning similarly. After talking to several different shops and reading online about cleaning sensors, I was at least sure about one thing, NO LIQUIDS! I hope this method works well for you, but I would NEVER recommend it. ; I found this quote which is correct but does not change my mind.
Contrary to the urban myths that propagate like viruses on computer discussion boards, no digital camera with interchangeable lenses has a exposed imaging sensor. All either have a glass anti-aliasing filter or an optical glass cover. With the right tools cleaning this piece of glass is no more dangerous than cleaning your lens' front element. But, the sensor is awkwardly located, and if you use the wrong tools you can scratch the surface of this filter or glass plate, which can lead to a costly repair. If you're fumble fingered you can also scratch the mirror or ground glass.
Be aware that for Canon, Nikon, Pentax or Sigma cameras, touching the filter in any way automatically voids your warranty.
Before doing anything about the dust in your camera, read your manual, re-read it, and then think very hard about everything that could possibly go wrong. If it seems like a bad idea, don’t do it.
These are both reason enough to careful who we tell to clean their sensors and how. It's risky. Even if you won't damage the sensor per se, you could still void the warranty and make the problems worse by smearing the glass or scratching it. Who wants to be the one they are pointing too when they screw their expensive camera and void their warranty.
A few years ago while Tim and I were both a WDW, we disused how to minimize dust to begin with. Its a new and painful issue for many transitioning from film to digital.
Tips:
* TURN CAMERA OFF BEFORE CHANGING LENS (the most important I think)
* DON'T CHANGE LENS IN A WINDY ENVIRONMENT IF POSSIBLE TO AVOID
* KEEP THE CAMERA FACING DOWN WHEN CHANGING LENS
* HAVE THE NEXT LENS AVAILABLE AND READY TO GO
* DON'T LEAVE THE CAMERA OPEN WITHOUT A LENS OR CAP FOR LONG PERIODS
When Tim and I were discussing this I am not sure if he was familiar with my level of experience or not, but these tips are all good to remind the experienced person as well as the novice. All the of tips apply to film as well except turning the camera off. That was one tip I had to remind myself a few times because I never worried about that with my film bodied camera.
I think this site had a balanced approach to the subject of sensor cleaning and balanced it with pros and cons of many different methods.
