Have you considered trying out a random name generator on the internet? It’ll give you a bunch of random interesting names. Alternatively, you could always try to go for something meaningful and/or punny like Darren Richard, the rich guy with lots and lots of money. (I know it’s a stupidly obvious example, but I tried).
