Seeking PhD in Economics/ development Economics

K

hello everyone
It's Kiran Khan from Pakistan. I have done MPhil in Economics. I scored 78% marks overall in MPhil and 90% particularly in my MPhil Thesis. My research topic was about financial market development and choice of trade partners. Are my grades fulfill the eligibility criteria to get admission in PhD in UK's and US's top universities?
Now i am looking for a PhD in economics or development economics and in this regard i need assistance and guidance how to choose the University/or supervisor and how to make PhD proposal which is the admission requirement in almost every university.
