Hello,
your post does not contain enough data about the project (maybe this is the meaning of the phrase "I am sending you the instructions for each"). For example, in order to import data from a csv file to Magento, you have first create the necessary categories and/or attributes for these products. Are these categories and attributes already created or not? The best way for importing is to use templates, based on the existing categories and attribute sets. Have you created these templates?
In any case, I can do this job well and fast. My bid is not only to create the necessary for the importing csv files from the existing Excel files, but also, to give you an Excel program with which you will have the possibility to create similar csv files in the future.
A few words about me: I'm developing VBA programs for more than 15 years and I'm teaching Excel and VBA (all levels) for 12+ years. The last 3 years I was working for some online sellers, mainly doing similar jobs like this one, and much more, including Magento tasks or scripts for Magento.
Looking forward to hear from you,
Kind regards,
chriskerpini
