Classifieds / Large commercial office project - finding sub contractors in Poland? [4]

Hello - we are not based in Poland but have been asked by an existing client who we have worked for in other locations around the world to carry out a construction project in Warsaw (Interior Office fit out project) where would be the best place to find names of good sub contractors for trades like:

Carpeting & Vinyl flooring
Ceilings
Partitions (plasterboard and glass)
Joinery (commercial joinery, reception desks, wall paneling, display cabinets etc)
Tea points and kitchens
Raised access flooring
Painting
Blinds
Electrical
Mechanical ( HVAC)
Data cabling
Demolition / soft strip
Fire proofing
Fire engineers

Polish tradesmen are best in the business so it should not be too hard to find the good guys! Thank you in advance
