I need to create a quotation / order form for a content writing service website, in which we have a single product that is content writing which have several attributes, most important is the number of words or pages. The price of our product will be depending on the number of pages or words + few other factors like the dead line etc...

We don't need to maintain stock inventory for this product.

While searching the solution for this in drupal commerce, I have came through this module http://drupal.org/project/commerce_option
Just need to know if some one has already implemented this module, please let me know if it is a solution or a part of solution to the problem I have listed above. And if it is the right module than how will we be handling product price through this.
