wodpress post php script

Looking for programmer to write a php script (or plugin) that I can use in wordpress. - I store a value in a custom field for each posts. e.g. 1,2,3,4...... (anyone of them) - I want a script or plugin, it will print different things according to the custom field value. e..g if custom field = 1 --> print A if custom field = 2 --> print B if custom field = 3 --> print C if custom field = 4 --> print D .......... My budget for this project is rather limited, since it's a real easy job. If your bid is unreasonable high, I will just ignore your bid. Thanks you :-).
