Price of live entertainment in Poland (Torun)

Hi All :-)
I recently sang (as a favor) at a polish birthday party and was asked by the owner of the venue if I would do a paid gig for him later in the year as a solo act, using backing tracks.

The problem I am having is that I have no idea what to quote him !
I have worked as a solo singer and with bands for years in the UK and have tried to ask some of the local musicians in Torun what the average rates are and although they tried to be helpful they were a little tight lipped about cash.

One of the local musicians told me that the music scene in Torun almost always acoustic and I should get a guitarist rather than a full band if I wanted to use it as a way of making extra cash.

My last duo in the UK consisted of myself and a lead guitarist using backing with the vocals and lead guitar pieces taken off the track. The local musician led me to believe that this might not work as well in Torun. The owner of the venue mentioned above however wanted to book me as a solo act.

Any ideas on how I can find a ballpark figure for solo/duo/small bands in the Torun area ?
I have tried to goggle it (in English) but to no avail.
Any thoughts ?

it really depends if u are doing it for fun or advancement in your pro career.

charge the same as u would in the uk, maybe.

how long is the set ?

what would a good DJ get paid ? ask for the same.

That is what I am trying to get an idea of :-)
In the UK I usually 2 x 1 hour sets approx. Sometimes less but rarely more and I charge £200 GBP. (for a duo) and about £150 for solo work.

I am assuming that this will be different in Poland and wondered if anyone had any idea of how different ?

Are you on facebook? I can point you in the direction of someone who knows a lot about this sort of thing if you are :)
