Bulk import dropshipping products to my LiteCart website from csv or Excel

I will need 1400 dropshipping products bulk imported to my LiteCart website by uploading a provided .csv file, including quantity price breaks (e.g 1 item for $10 each, 5 items for $8 each, etc). Images will be provided to match data on spreadsheet. I also need my dropshipper’s API connected to the website using the credentials given by my dropshipper.

Must be familiar with LiteCart and uploading product spreadsheets for e-commerce. Spreadsheet attached, but may need modifying for LiteCart’s parameters.

Work should take about an hour or two for people familiar with this kind of job.
