How can I get clear skin?

I have very oily, but also dry skin, I have outbreaks at random times, and my skin is not all one shade. I also have really big deep pores that stand out a lot, and these are all making me uncomfortable about my appearance..
How can I get clear skin? I would also like it to be a bit paler, so as well as staying out of the sun, is there anyway to make it lighten a few shades? Baring in mind I don’t have the money to buy a lot of things so I would be great-full for any homemade remedies. Thanks :)
