Gaussian is a commercial program, but perhaps your research group, department, or computer center etc. have purchased it already.
If you want a free general purpose QM program, you could consider Gamess-US.
When using another quantum chemistry program, you will need to slightly adapt the script to converts the default gaussian QM input to the program you're using.
