I have an android phone that is locked the screen. I forgot the number conbination to access it

I do not want to reset the phone as I have info and apps in there that I need. If you have unlocked an android before please contact me is an ASUS phone. I have data cables sim cards etc and I am a computer tech so anyway shape of form you can help I will pay you upon success unlocking and even removal of the screen lock. Thank you!
