Honestly, by doing it yourself the car will get more attention and will save you time over dropping it off somewhere and waiting hours/days for it to get done.

Once you've done things a few times it will go very quickly.

Oil change in <30min
Bleed all brakes <40min
New brake pads all around <1hr
New Muffler system removal and install ~3hrs

All you need is:
Good metric/SAE socket set ~$60
Clicker Torque wrench ~$30
pressure bleeder ~$60
Floor jack ~70
4 Jackstands ~$60
Oil catch pan ~$15

I have a compressor and airtools but only use them to remove wheels, you have to be careful not to cross thread or shear things with an airtool so always get the nuts started by hand first and do final tightening/Initial loosening with a hand wrench.
