NEED HELP FINDING A GOOD FOUNDATION

Hope

I have oily skin. All the foundations i've tried get greasy and do not last throughout the day. They start to separate and look cakey. Please tell me some good foundations that will look flawless and matte all day but will not look like i'm wearing so much makeup. I have olive toned skin as well. (i've tried FitMe Matte+Pore-less, L'oréal Infallible ProMatte, Tarte Amazonian Clay, Revlon ColorStay)
