As a designer & developer myself, I agree, the rebranding and new bootstrap template would take a week to deliver at most for ONE person. I'd charge ~$2,000 USD for something like this (30 hours at $75/hr).
It's not easy to find individual, most of them just disappear into a sunset: their PC died, parrot got sick, payment didn't went through, money didn't make their way to their bank account, and so on...
