Transportation from the Border

[abbubble]

We are moving to Guanajuato in April next year. We don't want to bring a car to Mexico and would prefer not to fly so we wondered if anyone knows of a driver that could pick us up at the border and transport us to Guanajuato, 2 adults, 2 dogs (1 small 1 medium size) and probably 4-6 pieces of luggage. We looked at driving a rental car from Colorado to the border and then renting a car in Nuevo Laredo but couldn't work out the logistics of changing cars at the border, hence the driver idea. Any thoughts on the positives or negatives of the driver option, how to make the rental car option work, or any other transport ideas much appreciated.
