Whether due to traffic or your quest to form the perfect butt-couch groove, it's impossible to get anything done in our vast city. Let someone else take care of the BS: Deliver LA.
Operating throughout LA (outer limits = San Diego and Santa Barbara), DLA's a 24/7 courier service that serves as a virtual personal assistant, albeit one you can't throw your cell phone at. They'll drop off/retrieve anything from forgotten keys to your latest script rewrites, plus more involved tasks, like shopping your grocery list or limited furniture-moving -- handy when you discover your chest of drawers won't fit into your Golf.
Pricing depends on speed, distance, and difficulty, the apex being when they rush you across town atop your couch, to preserve the perfect buttock cuppage you've worked so tirelessly to achieve.
