Hi Behzad,
Most of my free lance work is made up from this type of work with smallish companies wanting someone to produce reports and they want a better quality layout and graphics than Word or Publisher can produce. I would never export text from Xara but Tiff files yes to take into ID, I have only CS version of ID so I would not use PDF as an import. I have also used graphics from Xara as a template in ID, and thats about it, as ID has some great tools itself and along with AI most things can be achieved.
