I don't know if you can access the timer modules directly in HI-TECH C, but you can achieve the same results with the "__delay_ms(x)" function. To use this, you need to define a preprocessor symbol to represent the frequency of your oscillator.
The specifics can be found in the manual (here). If you haven't already, save this on your drive for future reference. And read through it, too!
If you have further questions, provide your updated code and ask away!
