Hey mate
You will need to show to them how you are going to sell your stock. They will accept a website but must be ecommerce and fully operational. These companies are not keen on Ebay at all so wouldnt mention that.
They will send you a trade application which requires all details of your business, Trading Names, partners etc. They also require Trade references, I had 2 in Spanish but they said not to worry (guess their Spanish wasnt up to scratch) also require Bank Details.
