There are several good write-ups on the web about sensor cleaning and many systems, kits and tools for sale. I'm sure everyone on this forum have done their part to keep those folks in business. In general I think sensor cleaning is a personal thing where some want to handle it themselves and others are more comfortable having it done for them. Either way, it's unavoidable eventually.
Another note: If you go to camera shows where Canon has a booth, they will usually inspect and clean your camera for free. Some shows have it, some don't. Depends on the size and sponsors of the show I guess.
IMO, sensor cleaning is simply part of owning a DSLR camera. If the user isn't comfortable touching their sensor, fine. But they should be comfortable using a blower because that may save them on location to fix a bad speck problem when other cleaning options aren't possible. The sensor is more durable than you think. It's covered by a transparent shield.
I think the info on lensrentals.com is great for learning more about this. It's pretty interesting. If their methods work on cameras that receive more abuse than personal devices, it will probably work for anyone. Here are links to that and also to another comparison of the various methods and systems available as well. I think they should offer a sensor cleaning service. They should be good enough at it after performing 100's (if not 1000's) of cleanings.http://www.lensrentals.com/blog/2011/05/the-lensrentals-lens-cleaning-methodshttp://www.lensrentals.com/blog/2010/04/how-to-clean-a-camera-sensorhttp://www.cleaningdigitalcameras.com/methods.html
Also, notice that taking your DSLR to the gas station and using the air hose there for blowing out your DSLR isn't listed as a method. Why? Well, as tempted as I'm sure you are to blow a 120+ PSI blast of oil+water misting air deep into your camera where it will contaminate everything and likely destroy all the mechanisms like a nasty hurricane, it's just not a good idea. And believe me, when you've worked a hour to get rid of one stubborn spot on the sensor and it just refuses to go away, this sounds a lot better than you'd think! (And don't go licking the sensor either!)
