Not sure if this hobby is meant for you if you don’t have the funds to provide for your Cham then he/she is in big trouble. This can become a expensive hobby. I hope that’s not the case and your just tight on cash rt now. Your Zilla mini bulb is no good and for the red and blue light from what I know tends to break very easily. You can go with a standard house light bulb for heat. But you still will need to provide a UVB light source a reptisun T5 HO or Arcadia bulb will do the job.
