I took everyones suggestions and worked them all together. I added two variations for the back side. not sure which one is best. It seems to plain with no picture.

IN and ON wall are listed as 4808. Floorstanding is listed as 4308.

the red and blue as already mentioned are too hard to ready and, in my opinion, don't look very upscale / professional

Ad #1 is the mailbox stuffer. That contains more pictures than words. Keep it simple. Don't confuse them, don't overwhelm them. Use high quality pictures that emphasize what they will possibly want. For example, if you're selling systems for placement in a living environment, provide a picture that shows how well you've integrated the equipment. Put some people, popcorn, even a dog in there to make it real. If you're selling a system for a dedicated home theater, dump the flat screens and get a picture with a 110" screen, theater seating, equipment rack neatly tucked away in the corner, etc.

Flyer #2 will be something you hand them after you're in the door, have discussed their needs, and talked about prices. The discussion and talking is where you impress them. The second flyer gives them something tangible to look at after you have left. Maybe you have a dedicated flyer for each tiered system to reduce the clutter on a page?

I would take a step back, and ask yourself what it is you want to accomplish with the flyers (nevermind the content at this stage). Then design the flyers around those goals, but realize the flyers are only part of a larger process of acquiring customers.

suggest a possible lack of care/attention to detail in the actual services to be provided. This is your initial contact with a potential customer - it ought to be perfect in that regard.

Also, if you offer follow-up "fine-tuning" or post-install "tweaking" services, which I think you should, based on my experience with a complicated HT install, then you ought to include it in the ad. FYI; my HT installer offered free followup, no limits, for a year; it was the best part of his service.

Regardless of what the reality is, you don't need to sell the impression that you'll be paying monthly visits for the next year to "tweak and tune". You don't want to lend the impression that it won't be installed and working right the first time. People's time is often more valuable than their money (especially with the audience he's targeting), and they don't want any indication that they will need to be on the phone troubleshooting or scheduling follow-up appointments to iron out wrinkles. Find some other way to word the 1 year no-fee support services.

Usually call/email my clients every month or so to make sure everything is going well.

proudly should not be capitalised
there should be a comma after company
TV should be capitalised after Plasma
So should dvd
There should be a : after 3 styles to choose from, not a comma, and either Floor should not be capitalised or standing should be. Consistency here is good.
There should be a : after 3 price levels, not a comma
There should be a space after the comma after Labor

All in the first paragraph.

followup thats often needed. Getting the right handshakes between all of my components, calibrating the video components, and tweaking the remote to my taste, took my installer (who is really good) the better part of a year (part of which resulted from my constant upgraditis).

On the typos, luvnhatemyA6 got some of it. There are several incomplete words ("vol"), inappropriate capitalizations, and bad spacing on commas. Of course, if you leave the .gifs in your ad, no male customer will notice the typos.

its just as important; if not more important than listing the model numbers of the items.

Certainly a reason to buy from you vs. a big box store / chain that may not really care if the customer is happy and everything is working properly a few months down the road.
