You might ask your local surveyors what they charge for that level of accuracy. Do you have line of sight? How good are surveyor's distance measuring setups? The VLBI guys look at a strong signal and back compute the antenna location. That may work better if you have more than 2 telescopes. The Earth is rotating so the time offset changes with Cos some magic angle. Don't forget Earth tides. -- These are my opinions.
