AbleCommerce Shopping Cart Software

I have over 2,000 products that have "Engraving Available".
The charge for Engraving is $9.99.
What I need:

1. When the product is displayed I need "Engraving Available" shown.

2. A TextBox where the user can enter the engraving text.

3. $9.99 added to the product price.

Sounds easy? Unless you have great knowledge of the classes and collections it is not.
If you can do it, let me know asap because if I can't get this soon I'll have to purchase
another ecommerce product, . . which I don't want, because I have experience with this one already.
Thanks

You could check with W2M. I have done similar coding, using template field select box for media type. I realize you want a text box, but the coding would be similar. On this page http://www.charitybaptistmedia.com/A-Ch ... -P863.aspx

The base product is a shippable product with the base price of $3.00. If you select CD, it is still a shippable product, but with a price of $4. If you select mp3, it is added to basket as a non-shippable product with a price of $2.
It retains those customizations when adding it to a wishlist and when moving from the wishlist to the basket.
