Camera Cleaning

[dasinc]

G'day everyone

Hoping someone can point me in the best direction to get my camera cleaned. Took it out last week to bluff knoll, noticed a spot in the photos, used an air blower to remove it.....all good. Then at the end of the trip I noticed several spots and I couldn't remove them with the blower.

I was too reluctant to try the lens pen (since I have no idea what I am doing and I've never had a camera before) but my mate said he'd done it before....long story short, I see more spots that image through the viewfinder!

I'd love a recommendation on where to go to get it fixed, and the best way of cleaning it for future reference.

P.S. I am pretty sure it is just on the mirrors?...I don't seem to notice anything on the images.

Thanks in advance.
