Design an ebook cover with 3d visual required.

Apparently I need a professional book cover design for my books. The existing ones can be seen on http://BrianIgoe.com. I'd just like to pick one of the books to start, Daniel O'Connell, the Last King of Ireland. If that professionally done website results in improved sales, I would want to do the rest as and when I can afford it. So to start, maybe 3 alternative offers. I always want everything yesterday but recognise that yesterday is unreasonable.... Details on me are on that website under "The Author".
