Zen Cart Guru needed

I need a Zen Cart guru to help me with the technical aspects of my shopping cart. I have to add values to categories of products and am unable to figure out this aspect of the shopping cart. I would like you to do this so that future edits to the values can be easily made and will make global updates to products in certain categories. The products and values are entered, I simply need them matched up and guidance via IM with issues I face. Please make a quote on this project as to how much you will charge to help me add the values and to give me about 1 hour of IM guidance.
