I am from Hong Kong, and worked as Engineer in Leighton Contractor for infrastructural projects such as Hong Kong-Zhuhai-Macau Bridge, Tin Shui Wai Hospital. Thus, I am very familiar with the construction process, certificate & QA procedure, underling government requirement & inspection etc.
My company is called Prozparity Energy also doing some trading, you can easily find it online. Thus, I believe I will provide the most promissing service to you, and could help your company to expand to Hong Kong market.
Regarding this task, I will need to know the detailed needs, depth of work and format before having a finalized concrete plan for you.
