I know you're looking for native English speakers. However, maybe a German with close to native level English skills will suffice? I'm German, living in Beijing, married to an American, main working language over the last 8 years: English, extensive experience in MarCom, web consulting/ content creation, and with hotel services & sites through my continued work in event management. Checked your to-be-improved site, pls view your messages for some suggestions. Thanks & best.
