Attention all fare gurus

I need help to price an itinerary Ottawa-Berlin-Prague-Ottawa.

*A would be the preferred carriers. Berlin and Prague can be inverted but a two day stopover in Berlin is mandatory.

Dates: 7-14 Apr
15-22 Apr
21-28 Apr

I tried to price it out and got $2247

Any suggestions would be most appreciated.

Thanks

Edited to add that the fare sought is the back end.
