Searching for a Beginner Board

Recently, I have started to surf and love it! I would like to purchase my own board and I am looking into some foam boards. I am around 110 lbs, 5' 6", female, and will be surfing waves at the highest of 5 feet. What size board would be the best and how long should I stay on a foam board before I can transition to a different one? Also, what is the price for the average foam board and how can I tell if it is a good board? Thank you so much for all of the help! It is very much appreciated!
