i am really sorry for not replying to anyone here, been busy with setting the new branch we opened.
We went with the epson Brightlink http://www.epson.com/cgi-bin/Store/jsp/Product.do?UseCookie=yes&sku=V11H665520 Opens a new window
It didn't cost us much and very powerful. cost approximate with setup about 4000$ with the 90 inch whiteboard.
I wish i noticed the sharp solution earlier.
thanks everyone.
