Powerstore UK

Hi, I recently purchased Powerstore and learned later that my client has a uk business paypal account instead of Paypal Payments Pro UK.

Now Im stuck. Although I really like this professional grade ecommerce, I read the forum posts that this system is only for US, but thats not a problem because I can change everything to UK by following the How To tutorials.

My client wants full registration, email receipts and order history and doesn't want to process credit cards directly from the website with SSL. Users have to register to buy, but pay with Paypal at the checkout process.

Please can someone guide me as to what I can do to setup the above requirements.
I have the full Webassist Suite.

Many thanks.
