Bharia ir right.
Samething I did for my mom. We requested a travel agent (forgot the name) to find someone who is going to DC and we will buy the ticket at the same time. There were new couple with DV and they were happy to bring my mom since they didn't know that many people here. Now, they are good friend here with us too. So, they will help you to find someone there either student or any other people.

Good Luck !!!
