Please help me select the Hikashop version

Hi Nicolas

I need the following two features...
1. The buyers should have the option to upload an image file during the checkout process.
2. Buyers should be able to repeat an order they have placed earlier with the option to modify the items and quantities and then confirming the order.

I have gone through the forums and I think both the features are available.

But I am not sure whether the essential version will satisfy both the above, or do I need the business version?

Thanks
