Chinese SEM for U.S. companies?

A Chinese company/colleague I am associated with specializes in SEM and SEO for Chinese companies. They would like to create a sub-company that would provide a platform for U.S. SMEs to test the possibility/profitability of fully entering into the Chinese market. Without giving too much or being knowledge-savvy about Baidu myself, what's the feasibility of the idea? Do better options already exist?
