I was recently invited to bid on a mobile development contract for a company in South Africa. After doing my research of firms that are local to South Africa, I'm noticing that my hourly rate is about 30% higher than the locals.
My question is, should I reduce my hourly rate to be more competitive with the local firms or should I justify my hourly rate? I was invited to bid on this contract so I assume the company knows of my work and is considering me as a candidate due to the quality of said work. Also, I don't know if any local firms are even bidding against me on this contract so I might be screwing myself if I lower my rate.
In support of a simple yes or no answer, I'm looking for case studies on rate adjustment in foreign markets to justify that answer. I am based in the US and this is my first contract bid for a company outside the US.
