Holy mackinaw! What a life! What an amazing life! From an interpreter to a cab driver! Definitely living an American dream.
So you are in California, right, pal? Do you even know how long it takes to get from California to Cancun and HOW expensive it is to drive a car all the way down to Yucatan?:)
Gas prices in Mexico now equal those in USA or Canada. You gotta charge several grands to make some profit if you really wanna work all over Mexico interpreting and pay for your own gas.
Ain't a smart business idea, chap.
Please reply in English:-) Would love to see your real skills (if any).
