Can I disassemble my 60D to clean the sensor and reassemble myself?

Hi, I have a really huge fungus section on my sensor and have already tried cleaning it in the service centre. But failed to get rid of the fungus completely. It keeps coming back. I don't really trust the service centre guys.. so I thought I would clean it by disassembling my EOS 60 d at home and clean the sensor myself. I have been watching a lot of videos and it seems not really a tough job.

Can anyone please help me with a step by step assembly manual or steps to follow, which will help me disassembling and reassembling my camera without any problems??
