You can test the program I have written demo in PHP at:
[login to view URL]!
Just change the string and see the result.
For the final project I can write an HTML form to customize the picture, i.e., colors, fonts (TTF), rotation of the test (2D), color and depth of the shadow under the text, fade rate, and anything else you may need.
All this in one day, since I've already written the program, but in case you need AJAX and fancy interface for modifying text and configuration, maybe I'll need one more day, but for sure less than 2 days.
The code is clear and the comments make it easier to understand.
Look forward to hearing from you.
