I am a publisher and want to create an online book store, what payment gateway etc should I take? What process should I follow to setup a decent website from where I can sell books?

By online book store, do you mean eBooks? If so, once you've set up your UI you can integrate http://bit.ly/1wdjTVT and start accepting payments within just 2 hours. Then once you create your online book store, you will have to look at how you want your clients to purchase your books. Do you want to set up http://bit.ly/1nKcVQkfor a monthly subscription, or maybe have customers purchase a one-time download for the ebook? Either way, we support multiple payments methods & options so we can help you set up the best payment options and give you the flexibility to choose whatever business model you want to present.

First of all, you need to design the User Interface/User Experience of your website. After you finalize it, you would need to integrate the shopping cart onto your website. Before adding the payment gateway, you would need to have a SSL certificate on your domain for security reasons. So the flow would be: Designing Website --> Developing the website --> Integrating the shopping cart --> Acquiring a SSL certificate --> Integrating the payment gateway. Choosing a payment gateway would depend upon the country you live in . Paypal is the universal choice

As has been mentioned prior, there are a lot of choices and decisions that you need to have in place before you can really choose your payment gateway.  First and foremost would be your E-commerce platform.  There are many choices out there and you have to determine which is going to be the best fit for you.   Once you have that choice made, you are now limited to the payment integrations that particular platform has for payment gateways and you will need to select from what they have available.   If you are developing your own E-commerce platform and need to integrate a payment gateway into it yourself, then the sky is the limit.  You will have to identify how much of the PCI burden you want to take on yourself and what regions you will need to be able to have merchant accounts in.  Those two factors are going to cut the list down pretty quickly.   If I can be of any assistance please drop me a message and I would be more than happy to provide whatever assistance I can in helping you find the right solution for your project.
