NS: that's exactly what I would HIRE AN ELECTRICIAN to do. the main service and maybe a sub panel. the rest of the stuff is simpler than your helmet was.
check out the lighting section for answers to a lot of your questions and if you don't find the answers start a thread or ask questions on the threads that are close to the questions and answers you need. also i've heard a few of the members posting in there are very very smart, but they don't have a lot of BED SIDE MANNERS so to speak. i've never read or posted in that section so my information is only second or third hand so decide for yourself and report back cause i know a lot of great electricial members here that might have started to post there. i had maybe half of my clients that were contractors that were like that and i was their GO BETWEEN as their REALTOR. they could build a Taj Mahal, but they couldn't give a paying client even a smile.
ok enough of that and just a warning that isn't always necessary. here's a member (Denwood or WOODY) that has a ton of lighting stuff in his thread and i can vouch for him that he is a great person too with plenty of bedside manners.

since you now how to go in your GJ profile if you want to go back in and click on Avatar you can download one of your favorite pictures as i have with a welder in South Dakota's bison made of old scraps.
you'll have to teach me some welding tips and i'd like to hear more about that new helmet cause i hate the idea of a battery controlling my work if it fails. i'm guessing you just didn't come off the weld quick enough, but i'll defer to those that weld and lay dimes better than me.
make a plan for the lighting and like i mentioned you might have 2 areas wired up for a 220 even if you only have one hot at a time in case you move things around you won't have to move your entire wall or shop of STUFF.
Happy Holidays to you and your family.
cheers
