Dont book the apartments/studios from the model agencies they try to increase prices for shootings.
Look in google for prague apartments. You should be able to find 3 bedroom apartments in the very center of prague for no more then 80-100 eur a day.
last time i shot in prague i had this apt at Wenceslas Square (in the middle of the center)

I paid 80 eur the night. They are "adult" friendly and have shootings all the time, besides the models can find it very easy.
Offer between 150-200 EUR for a solo shooting some better known models may charge 250EUR but no more. Normally those models are used to shoot half a day or longer for that amount. So if you are a fast shooter you can easily make 3-5 sets for 200 EUR (Including video)
For lesbian scenes dont offer more than 300 EUR and bg between 300-350 EUR.
btw. this is the most reputable model agency in czech republic:
http://www.model-mania.cz/
but actually it does not matter which agency you use, as they all charge the same (20% of modelfee) and most models are registered in every single czech agency.
if you need a makeup artist...they charge between 100-150 eur a day. but just tell the agency the models have to make their hair and makeup on their own, (they are used to that) so you also save the money for that)
