Looking for a Travel Agency that has been accredited by the Czech Republic diplomatic mission?

I have a Russian pport and I am living and working in Texas with a work permit, and I do not want to have to appear in person at the Washington DC Czech Emby to apply for a visa for the Czech Republic. On the Czech Emby website it says "you can submit visa application through a travel agency, provided it has been accredited by the diplomatic mission." Does any one know of a travel agency that would quality?
