Need help finding a diamond

[newbiehelp11]

I desperately need help finding a diamond( I posted earlier but thought it would be better to start a new thread). My budget is 5k for the diamond with total of 6k for the entire ring. I am looking for a princess, 1.15 and higher, excellent/ ideal cut, I color or higher, SI2 or higher. Any ideas/options/advice is very much appreciated.
