On ODesk, you can find decent designers willing to work for $15/hour on Bootstrap. It's cheap, and the really good ones can easily do up a custom site in a work week or less, provided you have some existing assets (logo, screenshots, boilerplate text). Some do better work than others, but surprisingly, it's no longer a "get what you pay for" thing when it comes to outsourcing. Some are college students building portfolios, others are outside the country and willing to work for less. My suggestion is to first hire someone to design a logo (even if it's typeface-only, and reject any Lobster submissions) and a color palette, usually less than $100. Given that, a bootstrap pro can have you a custom site in a few work days.
