Hello Again, Phil,
We worked together a couple of months ago & since then, I've worked A LOT on responsive websites. I've even specialized in a framework called Kendo. You can learn more about that at kendoui.com. The key point of awesomeness of this particular product is that you can make websites APPEAR like native apps! If the browser is on an iphone, it looks like an iphone, likewise for WP, Android, Blackberry, and a couple of others. Truly awesome. Now...that would take quite a bit more time & cost more money, but as I recall you like cool new technologies like this. The price that I quoted is for a normal responsive website. I made my own website responsive and integrated it with Umbraco (CMS) over the holidays.
Thank You,
Brandon Osborne
