The highest I've heard technicians get paid in Houston is around $25/hour. This is as a chemo infusion tech at MD Anderson. However, most technicians I know (including myself) are happy with what they make and would rather stay as far away as possible from chemos, even with all the safeguards and precautions in place.
Since you have done a Pharmacy Technician program, and are most probably IV certified through ACPE accredited training, I imagine you have better odds than I did of negotiating a wage better than $14 an hour. I would advise you to start volunteering in the Pharmacy of a hospital you might be interested in being hired at. If you are able to impress through hard work and quick learning, you shouldn't have any problem in getting hired.
