HELP . beach themed bedroom?

so . im 17 , and were moving to a new house and all my life ive always wanted to you know really have a room with a theme around it . at first iwas thinking hollywood glamour on animal theme cuz im in love with zebra prints but i know so many friends who have that . while i was looking at lamps i noticed this cool table lamp with sand and seashells in it then i thought HEY! why not do a beach theme or hawaiian theme since i do go to the beach just about everyday .but when i look for items to go with this i cant really find any ideas on how to decorate this . i dont have alot of money but i do have a job so any ideas would be helpful . or maybe even craft type ideas . OH and anyone know where i can find a beach or tropical related bed set ? unfortunatly the walls are like a light pastel green. ok thanks!
