Hey eComm gurus!

I'm trying to write a business plan for my eCommerce business. Is there an industry conversion rate that I can use as a benchmark?

For example, say I get 1,000 visitors to the site. Is there an industry standard conversion rate I can use...say 3%, that will tell me that for every 1,000 visitors I should expect 30 of them to purchase something from my website?

Where would I be able to get this info?

Need this figure to put my banker at ease so he can lend me money

Thanks!
