Law / Help with getting an address in Poland to open a Polish bank account [6]

I need some advice please. I need an address in Poland in order to open a certain kind of Polish bank account that I need. The bank requires a Polish street address that isn't a hotel or hostel. However at the moment I don't really want to establish a home in Poland but I'll arrive there at the end of the year and stay about a year. The bank said I don't have to live in Poland but that I DO have to have an address for mail and service of documents and it MUST be a residential address not a PO Box.

I'll be in Poland in about 6 weeks time and want to get the account organised then so that I can start putting some earnings there prior to my arrival later.

My first thought was to simply rent a cheap room for a few months even though I'd be leaving it vacant. I can actually afford to do that but it seems like dead money.

Does anybody have any alternative suggestions?

Also, as I don't speak Polish and don't know the lie of the land, I'm thinking I'd like to pay for the services of someone who knows their way around, speaks Polish and knows how things work. What's the best way to find such a person, and what's the likely hourly/daily rate? I'm thinking an enthusiastic student with some summer holiday time on their hands might be glad of some extra cash. Where's the best place to find such a person BEFORE I arrive? In Asia, where I'm passing through at the moment there are swags of agencies that provide ''facilitators'' to help business people get things done but the concept seems alien to many parts of Europe. When you advertise for such a person, people in Europe seem to think you've got some kind of secret agenda, when all you really want is to hit the road running and get things done. Any advice will be welcome.
