OT projector recommendation question

Greetings folks

this is a slightly OT projector request for a projector recommendation.

can any one recommend a high brightness projector with great contrast –

I have not really spent the time to delve into dark chip 3 and what not
but I have a client who needs a projector for theater use (thus needs to be bright)
AND is not happy with the contrast they are getting –

we are currently using an Optoma Ez Pro 758 –
3000 lumen with a 2000:1 contrast rating

oh ya – it would be good if it were free!
(ok say $2-5k)

many thanks
