Help and advice needed ! Texturing a chimp !

Hi guys, I am somewhat new to blender, so forgive me if this seems like a stupid question but how would I go about texturing this with photo realistic textures. This is only the sculpt currently, I am going to do the retopology in the next couple of days. I was wondering if anyone had any advice on the matter or if someone could point me in the direction of a good tutorial ?
