Jake... I'll just give you honest opinions and wish you the best of luck...
First of all, you said you had some detailing experience and so do some of you other guys... while that's a +, your problem comes from not having enough experience as a paid detailer in your current location.
This is where the pricing problem comes in. Personally, 95%+ of my clients, who do pay upwards of $200-300 for a detail, are people I've met through car forums, meets, etc. In other words, these people care about their cars, and word spreads around. The other 2-5% are "average" people who do care for their car, but it's just too expensive. They have their car detailed anyways, pay what I ask, and very very rarely come back.
My point is that you can't simply expect to open up a detailing business, that charges 2-4x as much as the "hacks" do around you, and be successful, not immediately anyway. Your best bet is to familiarize yourself with some car clubs in the area, and/or advertise to a higher end group of clients. In the meantime, you can only expect to charge what others are charging around you, whether you do a hack job or not is up to you. Personally, I would do a half-assed job on an Escalade for $150. Coupe's pricing might be a bit higher than mine, but I similarly wouldn't go less than $300 if it involves polishing at all.
As for the old lady, or anyone else asking why you charge so much (even though as I said before, IMO you still don't charge enough if you're polishing an Escalade for $150), tell her/them to stop by and you'll show them why.
I can't tell from the pics you posted, but assuming you have the right technique, products and results as many autopians do, you can easily choose a 2'x4' area on any potential client's car... do a 2'x2' area to show them what you can do and why you charge what you do, then QD the other 2x2 area and apply a wax, to show what the "hacks" do... I have done this a few times and have won the client over 4 of 5 times (1 guy said, "so what you can just see a few lines, paint still shines" :grinno
They can easily see the condition the vehicle is currently in, "hacks" results, and your results.
You can even have the person get half their hood detailed by one of the other shops (make sure they do a bad job though haha) and then do the other half showing the difference...
Anyway, sorry for long post, just trying to help out from my short 2 years experience
The plants and paint are a good idea btw... definitely improve the walkway/driveway in front
Good luck
