well for me. I’m glad I use the agency. It was only 8000 ฿ and it saved me a little bit of hassle just like I don’t wash my own dress clothes I take them to the cleaners let somebody else do it 😁
If you need somebody use a company called “settle abroad “out of Pattaya they only charge me ฿8000 to do my application very easy to send all my documents to them through Google Drive. They were professional they corrected mistakes that I would have made if I had done the application myself I received my DTV Visa within five working days and again the total cost for their work was ฿8000 
I will tell you in dollars what it cost me if that’s what you’re asking the cost. The agency charged me $236 for their services. The embassy charged $450 for the visa and the Muay Thai school charge me for three months. $354 so the total cost was $1,040.
yes they use Google Drive and what I sent through Google Drive was copy of my passport, a recent passport photo, I sent them six months of bank statements(even though they only asked for three) copy of my electrical bill where I live and a copy of my California drivers license and they sent me a information sheet where I wrote all my info on and that was it and within a week I had my DTV Visa and they applied for me in Los Angeles. They did completely everything and also I’m on soft power Muay Thai and they set that up for me also and I just sent payment to the Muay Thai school.
