What are some things I need to know for a hip peircing?

I plan on getting my hip peirced. I already have had my tounge peirced. Now i want a peircing no one in my school has , so i can be the first. Now i know it hurts but some say its just the pinch. I need to know how much it is for both sides together. When iI get it done will it not last long like some people say ? If i want to get rid of it , do i need to get it surgically removed ? How do i change it , if i want to change the barbell? some main qualifications i want to know before i get it done soon. Thankss
