The only legal source for Snow Leopard is from Apple, on a retail installation disc. Apple still sells it from $20 (I thought you already had one)
http://www.apple.com/shop/product/MC573Z/A/mac-os-x-106-snow-leopard
After getting the official disc, you can create your own USB flash drive with bootable installer, if you need one (instead of using the actual disc directly in your Mac's optical drive). But I would not trust a source on eBay. They could potentially add malware to the installer.
I'm not familiar with using a USB flash drive to run Mac OS X installation. There should be no problem with selecting an external drive as the target, when starting up from standard installation disc. El Capitan does not matter, if the target external drive is erased.
Unfortunately all I then saw was a grey screen with no apple Logo???
As noted in previous reply, the originally pre-installed Mac OS for your iMac is important. It seems like your iMac originally came with Snow Leopard; it shipped with an installation disc for Snow Leopard. If that pre-installed version is 10.6.3 (for example), the version of Snow Leopard on the installer cannot be earlier than 10.6.3. So, if the installer you have is for the original Snow Leopard release (version 10.6 dot nothing), you can't use it on an iMac that original came with 10.6.3. That may your problem.
