Girls, what can I do to get my crush to notice me?

Well, You are not a slave, dude. Why are you acting to be one? You don't have do such things just to kiss her feet!! Go straight to her and tell her that you love/like her and you really care about her and wanna be with her but this slave thing is not gonna work anymore. You got a lot of girls out there, man. There are many who will understand and like you from their heart.
