Hi There
It seems like your client is requesting something that is considered to be unethical in terms of search. Stripping it back, they are asking if it's Ok to deceive Google Places by creating fake addresses, plus indicating that they are happy to display fake addresses to searchers.
With a well optimized Google Places listing and a well optimized webpage for the listing, it should be possible to show up for more than 1 of those home services.
My advice would be to avoid doing what they are requesting, as not only is is bad practice, it does present a real risk of being caught out, possibly during the verification phase that Google do, bound to get flagged up.
Hope that helps.
Regards
Simon
