WooCommerce daily API import from CSV files

I have some CSV files from suppliers that I would like importing into WooCommerce.

Each file has slightly different layout and we need to take SKU, price and stock quantity from it.

We apply multiplier to the price, a prefix to the SKU to match with skus in dB, and update stock quantities if over a minimum threshold.

All skus not in import file should be set to quantity 0. I have four different domains which between them import from a total of 9 different files.

If you have experience of WooCommerce please place a bid and let me know how long and how much it will cost.

Thanks
