As other have said it's a bad time to start reloading.
Primers that you should be able to by for 35.00 per 1k are now going for 300.00 on GB. I know do buy them right? Good luck trying to find some. And if you do, it will still be much higher than normal times. Powder is the same way. Now would be a good time to read and learn as much as you can. I pray that in two years things are back to normal. I'm not holding my breath.
As far as time goes, you get out of it what you put into it. I guess the real question is what kind of accuracy do you expect? I have very good equipment, I paid a lot of money for. I spent the money because I am able to buy my time back with it's use. I can throw 200 powder charges in a hour with seating the bullet all charges are within .02 gr from one another (not a typo one kernel of powder). I would venture to say I average 50-75 rds an hour all in. That's cleaning, full length resizing, trimming/chamfer, cleaning, annealing, priming, powder, seating bullet. I expect single digit SDs and my groups sub .25moa. Those are my expectations does not mean they are most people's.
Side note, if you have 5k of ounce fired 300wm start selling that off and offset the cost of equipment to start reloading. My .02
