Questions for a tattoo idea?

So I have this idea for a tattoo I'd like to get sometime soon. I'd like to get the phrase "Strive to be different" written in spanish though. If anyone knows how to translate that phrase correctly that would be much appreciated. I'd want to get it on the middle of my back in cursive black font. I'm not sure of the size yet but not super huge. If possible to figure out from the information I've given, how much would a tattoo of this nature cost?
