I have one GFI in the garage near the door to the house and want to add more along one wall for now. The current outlet is on a 15 amp breaker.
I don’t want to cut drywall add the wiring/boxes, repair and paint (too impatient 🤪

, so my plan was to run grey 1/2” conduit to surface mount boxes and run individual 12/2 wires, as needed to daisy chain them. The existing outlet is flush to the drywall, so I’ll have to extend it out and then start the chain.
The obstacles are the panel box pop out, two outside and three inside corners from the GFI to where I’ll stop. I’ll run short 90* sweepers in the inside corners and LB boxes on the outside corners. The panel box is up high, so I can drill two holes below it and run the conduit through it.
With a 15 amp breaker, how many outlets can I add? None will be in constant use, but I want enough of them spaced along one wall so I always have one as needed (I was thinking five or so).
Any other ideas how to add the outlets, besides calling the electrician?
Here’s a rough drawing of the layout.
