I have a catalog of over 30,000 items and nearly all of them have attributes.
I will give you:
EXCEL spreadsheets with all the data
I will upload the pictures.
I will upload the products into my zencart database.
I will make a backup.
You will modify all these products using the excel spreadsheet to arrange the data the way it needs to be to get the attributes loaded.
I have attached a file with a sample of the data you will be provided
