I would use the drive way if it gets the most sun and just grow in massive air pruning pots. You can buy the material and a sewing machine and make them yourself. Grow 10 - 20 big plants using lots of organic techniques including your own ACCT brews and you'll be on to a winner. I would leave the lawn alone until you are 200% sure you know what you are doing more.
Get that 1st year grow under your belt and then may be go bigger next year. Your setting yourself up for a lot of bad feedback if you keep posting with the attitude of becoming a pepper sensei in the first year. If however you do, I want seeds! But bear in mind some people who have offered advice to you already across the threads you have started have been growing big for many years and still suffer from a bad season from time to time. It's pretty mush a given that on your first year you will make LOTS of mistakes, so write them down and change them next year.
I feel you would be better off trying to grow 10 - 20 big plants rather than 100's of smaller plants. That's what I would do if I was in your situation. But good luck on you decision when you get there. At least your trying to work out the best method, everyone can see that. But don't forgot to actually grow yourself some peppers along the way, actions speak louder than words and all that.

Sorry for a double post- just thought it might help.
I have a Moruga Scorpion growing at the moment which is 43 days old and this is she:
I'm not being a show of at all - I'm not like that Joe, just trying to help. But you can see the difference between yours at 2 months and mine at 43 days. This too is the first year growing peppers for me also, so I am not Sensei but I have tried to start with the very basics and get them right or as best I can and then move on as my plants move on.
You can see and have been explained to about the importance of quality light, soil and a watering schedule so try and get those down pat and then if you can keep your plants alive until they are big enough to withstand out doors then look at going bigger.
Like I said I'm not ribbing you, just trying to help. I have been following your glog from the start and have read some of your other threads so I have a interest in seeing/hoping you succeed on your venture.
My Ma always said if you don't know just ask, so +1 on that my friend. But keep the dream real so there ain't no spill!
