hong kong company setup

why do you think so?
there is no disadvantage in having one in HK.
well, you have to make a tax declaration but the whole process can be outsourced (from accounting to auditing)

What are the average maintance costs for a HK company? say I have only 100 invoices a year?

That depends on who you let do the job and how much of the necessary work you do.
Like someone would have to talk to the auditor who will ask questions and provide (maybe create) some extra paperwork. You can do it yourself or have someone coping with that (I do the second).
Your annual costs will add up to a small to medium 5 digit number of HK$.
It also depends if you pay tax in HK or want an exception (second is more expensive because you deal with the tax department directly, not just a private auditor)
