Setting up attributes for alphabet

I need suggestions on how to set up attributes for bracelets that will include Alphabet cubes. Bracelets can have a name of choice. Nine letters are included in the price of the bracelet, any letters over 9 are $5.00 each. Customer will also need to indicate name - should that be done in comments?

Normally done with attributes as in the demo porducts you can review **HERE**

This thread is very similar to what you are asking?? > http://www.zen-cart.com/forum/showthread.php?t=150194

After seeing the demo, I think I've figured out an option.

I've set the option name as "alpha characters", option value as "text" letting the customer enter the characters requested and then the price per extra letters and number of free letters in the prices attribute section.
