I'll assume you want pulley only information rather than any other options. You will probably learn far more about characteristics that make good pulley systems from a link such as this one:

Friction Testing and Pulley Systems in Vertical Rescue

There are many expensive pulleys, some cheap ones but there are trade offs with each type so it's important for you to find what will fit your specific needs and budget.

Imporant considerations for your use:
Will you need a lock on the pulleys themselves? If so, rigs such as the CMI uplift set or sbi pulleys offer that. Integrated locking systems in pulleys raise their price significantly.

Do you need a compact set? If you will be carrying this around finding something moderately compact and light is nice, but you sacrifice efficency.

Will you leave it in the system during slacking or will it be used to rig long lines? If so, it must be significantly stronger than one used to rig shorter lines.

How long of a line will you be rigging and will you expect to have help pulling it tight? If rigging a medium to long line solo you may need more than a 4:1 pulley system can provide so a system with higher mechanical advantage may be necessary.
