I've using a Canon 5D Mark II for quite a long time. The performance is impeccable and the quality it delivers is up to the par to other professional cameras.

I would recommend you to grab a 5D mark ii at salam, which will cost you around 10,400 riyals, and a 24-70 mm f2.8 lens which will be around 7000 riyals.
This lens is a powerhouse and will deliver you results just the way you want it to be.

Then there is Canon 1D Mark III, which, if you are a night and low light photographer, is your only bet to acheive clean images.
Coupled with a 16-35 mm f2.8 it delivers unparallel performance.

And if you want to learn about photography, you have to start with light metering. As trivial as it may sound now, the metering, which calculates and determines the amount of light it should let enter the camera, can be really stupid at times. The camera always mixes up the contents of the frame and try to make it equaivalent to 18% grey, which in result produces wrong results.

So I have just given you something, from where you can start your baby steps. Now google fiercely and make your learning curve steep ;-)
