Integrating CCAvenue, would make you guys the best right now. I've been using sites like JustRechargeIt and the official site's of the providers, since i am not charged an extra penny, and they accept All payment methods, except alertpay and other payment providers that "We" use. So, here's the point: Big sites have netbanking, cc,dc etc, but doesnt have most common payment providers - thats the minus point for them.
You guys, have all the common payment providers (except paypal right now) which makes you different from them, but still, you must have those facilities such as netbanking etc etc.
My suggestion for you is, keep the design like this, its simple and sexy, just add CCAvenue or any other billing solution, so that you can have "ALL and ANY" type of payment options.
