I have a customized osCommerce shop (MS2) set up successfully with a few contributions. I am having difficulty understanding the setup of the PayPal IPN v1.1 contribution (public keys - private keys, etc.) as well as how to setup shipping charges so they are automatically integrated into the payment.
The ideal candidate for this posting should know about osCommerce and the setup of the PayPal IPN Modules (not the basic pre-installed payment modules).
I am wanting to learn how this is done correctly. I am looking for someone to help me for appr. 1 hour guiding me through the steps of setting up the PayPal IPN v1.1 Contribution as well as any shipping modules needed. (I do not want it setup for me as I will not learn this way) Communication can be done via Telephone, Instant Message or a Voice Program on the internet.
