Dust between lens elements

Hi all,

I'm looking to get my travel lens and camera cleaned.

The lens is a Canon EF 24-105mm f/4L IS USM and, despite my best attempts at cleaning and keeping it safe, has acquired what looks like hair and dust somewhere near the rear element (have tried both air and microfibre cloth to remove it). Does anyone have any experience with London (or nearby) based photo shops? Or am i best off just sending it to canon? Would anyone know if this is part of a standard lens clean, or would i have to go for a pricier repair/servicing option?

The camera itself (5d mkii) also appears to have dust somewhere between the mirror and viewfinder (though a recent very windy trip to iceland actually helped to remove a bit of it). This doesn't affect picture quality at all, but I wouldn't mind getting it sorted if there's an easy way (without taking the camera apart). I always thought these bodies had a bit better weather sealing than this :/
 
it shows up as lines and points against blue skies. i'll try and put up an example when i'm back home. Will give cam-rep a look.

Thanks,
