Here is a link to the different training programs in Texas.
If there are any that are provided by nursing homes in your area there is a good chance that you could get a job there and they will pay while you take thier nurse training course.
This site might be helpful with other questions:
When I became an aide I just emailed the HR departments of the nursing homes that offered courses, found one that was starting a training course soon and my first 3 weeks on the job were just classroom work - then the Red Cross came out to our site and we tested there.
I wouldn't want to do an online training course, but that is just my opinion.
