This might help some, they include some icc profiles.

However, 

as far as targets go, you are going to be better off spending some cash 
on a calibrated target. I use an X-Rite Passport Colorchecker.

There are others. Just understand that it is not going to be practical 
to create your own targets as you have no calibrated reference.

As far as color space profile goes, that is going to depend on your 
display (which in all likelihood is sRGB) and your intent regarding the 
sort of work you are trying to do and the software you are using.
