Fastest way to get my CDL in Houston?

I purchased a semi truck last year that has been doing work out in West Texas but I am ready to get out of that particular business and would like to avoid having to pay another driver to bring it back to Houston. It would be very convenient to have when my drivers are on break and the truck needs brought to shops etc.. for maintenance

Hoping to find a private instructor (if that’s a thing) who can help me expedite this whole process, but there is little information online pertaining to getting a license outside of the usual trucking schools.

Any information would be appreciated! Thanks!
