Starting to surf.

I have decided to start surfing and making it my primary sport as well as compete one day. I am 19 years old. As I live an hour and a half from South Padre Island I decided I could fulfill this necessity. I plan on taking surf lessons or doing a surf camp in the next following days. Then, getting my own surfboard and starting to practice myself. What type of longboard should I start with?
I just wanted to share that and receive suggestions/comments. I am around 5'10" and weight around 121 pounds.
