PayPal account type + Other payment questions

Hello all,

We're in the process of setting up our new OpenCart store, as well as establishing all the early stage items for a brand new business venture. We're a few days away from opening up our business bank accounts, so I wanted to pose a few questions to the community regarding PayPal, and other forms of payment processing.

A breakdown of our online business will be one that sells physical (shipped) goods at a fixed price. At least initially, there will be no subscriptions. Monthly sales volume will be in the $10,000+ range.

We've been looking at 2 premium extensions to better extend the checkout process:

1. http://www.opencart.com/index.php?route ... n_id=16711
- For Social openauth logins to be used to register/login to the store during checkout.

2. http://www.opencart.com/index.php?route ... on_id=9132
- To significantly simplify the checkout process.

And additionally, we plan on using 2 payment processors:

1. Stripe for all regular credit card payments.
2. PayPal for PayPal payments, and/or secondary processor for credit cards.


With all of the above in mind (extension + processors):

1. Which PayPal account type would be suggested for maximum benefit to us (the merchant)?

2. Ideally we would like to find a PayPal processing method that works like Stripe, where it keeps the customer on YOUR site and does not redirect them to PayPal.
- Is this what the iframe PayPal extension would basically do?

I guess the behavior of either payment method is going to be dependent on the Quick Checkout extension that I reference above, as that's going to change the default functionality quite a bit.

Any info or suggestions would be greatly appreciated!
