Add Paypal to a Website

The site is specialist Iris nursery in Spain, and offers a large range of irises which may not available elsewhere in Europe. The site has been set up with a shopping basket and an admin backend for CMS control of pages and orders. Currently completion of the check out stage results in three actions, email to website owner (details of order placed), email to website user (confirmation of order) and data written to database, orders. she then contacts the purchasers with details of how they pay for the iris, bank transfer, cheque etc.. Its slow, time consuming and she has lost orders because of the complex process. My client would like for people to be able to purchase direct via Paypal (either with a Paypal account or using credit cards). We would still like an email to the website owner (order details), email to customer (confirmation of order and payment) and order details written to the database to continue with this extra feature. The site is written inthree languages English, Spanish and German and so the Paypal pages would need to load into the appropriate language. The site is written in ASP. In the Autumn we plan to redesign the look of the site so there may be additional work for the right bidder in implementing that design.
