Can I provide other payment channels than iTune account such as credit card processing on web site and later direct the clients to download my app from iTune?
You should e-mail Apple developer support. I'm almost positive what you want to do circumvents their policy; they want direct control over all transactions that result in the user getting an app.

As it should be considering all apps are being purchased through the app store.
