If you're struggling to find a solid available .com for your startup, I'd encourage you to check out my free service, Lean Domain Search [1]. The site asks you for a keyword then pairs your keyword with 5,000 other words and instantly shows you which are available. For example, if you search for "food" [2], it will pair it with "free" and check "FreeFood.com", "hub" and check "FoodHub.com", and so on, and it also allows you to sort the results by length or popularity of that additional word. With a few searches you should be able to find a great domain, saving you a lot of time and potentially a lot of money.
