Talk to your lender and title company. Get an explicit written list of their requirements for things to be shown on a survey and their certification requirements. Most folks will look at you like a cow staring at a new gate regarding the certification requirement. When you get the list push back on everything requiring locating anything farther than 5 feet from the proposed property line and any certification higher than a simple Texas Board of Professional Land Surveying certification or possibly a Texas Society of Professional Surveyors Category 1B (NOT a 1A). There is no reason to survey a house in the middle of 25 acres for the purposes of a partition. This is what appraisals are for, though you may want to have the survey stake the boundary lines every 100ish feet so the appraiser knows where they are relative to the improvements.
When you're done with all that, call James at Jones Carter in College Station and have him do the work. There are two very good registered surveyors there (James being one and the department manager). You will pay more on the front end but you will greatly reduce the risk of paying attorney's, surveyors, and your own headaches in a boundary or title conflict later.
If I still worked in the area this kind of thing would start in the $3k-3,500 range and go up depending on research (Madison is a fruitful place for not having been surveyed since the 1870s), field conditions (sight lines arent everything, plowing or mowing property often destroys title evidence), lender and title requirements, current owner orneryness, parent tract size and configuration, and distance from the office.
If someone quotes you a few hundred to survey your dream/retirement rural property, like was suggested above, feel free to take it at your own risk.
