I am looking for some advice and tips on how to go about uploading hundred of thousands of products onto a Magento store in my lifetime.
Today, I discovered Magmi which is a godsend for uploading CSV files at a fast speed however it still requires you to manually enter in the data. I have timed myself for each product I add, and on average I take about 5 minutes. I have quite a few extra product attributes :) So if you do the math, 5 minutes times lets say 10,000 products or more, well you get the idea.
I'm thinking of hiring a freelancer that will write a script to scrape the appropriate data from my suppliers and export it as a CSV file however since I have quiet a few suppliers this might be expensive. Also some of my suppliers provide spreadsheets of their products, while some don't.
Is there an efficient and productive way of accomplishing a task like this?
