Runnin it in FF and aesthetically it looks great. I love the FB and Twitter links. The content could use some work, as it is kind of a tough read. Keep in mind, if you are in love with what you have then disregard, this is just one person's opinion.
Is it two different companies? If so, split the pages and/or combine.
The first paragraph is the "about us" section and it needs to be strong. Instead of starting it with A, try We are a sm....started by two crazy people who gave up the Fast Food lifestyle and traded it for sustainable living, and a guy who has the same love for the World's Hottest Chili Peppers as they do for growing as much of their own food as possible.
IXII or 911 for the super hots that we could not find fresh locally. To me this doesn't make sense. What are you trying to say? The delineation between the roman numerals and 911 was not the first thing that came to my mind. I just thought it was called I-X-I-I Produce. But that makes it tough if you want to be called 911 because for all the new people to your site you will have to have 911 right behind every IXII. That gets really redundant really fast. Also, the Roman Numeral for 911 is CMXI. So this may cause further confusion down the road. Maybe 911 Produce or IX-II Produce, or something along those lines.
What is not personally used during the week, we offer to others at local farmers markets during the week. Redundant: during the week, during the week. Try, "We offer plenty of fresh produce at the many local Farmer's Markets in the San Diego Area. To find out if we will be in your area, check the blue "info" tab directly to the right of this box.
I would close with something that drives the point home like if you are looking for the freshest produce or want to give the burn a shot come check us out at the next market!
Like I said, if you are attached just disregard. This is just my opinion if I were doing the exact same thing as you are.
Parting shot, just make sure that every image you use on the sight belongs to you (i.e. you took it or have the express permission of the owner). That is the fastest way to get shunned from this site.
Good luck
