Where to find a good dating coach?

Iím into this girl right now but I feel like sheís too good for me. Sheís a foreign girl that I met while surfing. I immediately liked her when I saw her but she doesnít know that. I asked for her number and asked if she wants to go out with me. She agreed and we went on a date. It was the best time of my life, honestly. My problem is I donít know what to do next. How do you make it official with someone who doesnt come from the same background as you? I was planning on getting a top foreign dating coach to help me make sure I get this girl to agree to be my girlfriend.
