Looking for an online store to buy a: personalized (4 letters), messenger bag (preferaby pink!)?

Question

This bag in carnation pink is ideal! :

However, I MUST be able to personalize 4 letters. This one only does 3.

I don't want any websites that sell you those cheap bags that you can personalize for party favors or something.

Looking for under $60.

Need it for a teenage high schooler.
