I can think of absolutely no reason why a capital letter would be required, for the word 'county', in your sentence. It's definitely lower case.
While I might not use commas in exactly the same way as you do, I'm pleased to see that you're trying to write as you speak. It makes things so much easier for the reader ;-)
My use of English, here on AB, is far from perfect but I've learnt that it's best to break long sentences into two or more shorter ones.
For example, your second paragraph (above) requires a 'sentence ending' after the first five words. Since 'can' is asking a question, a pedant might insist upon the use of a question mark. But most guides to the use of English would probably advise a 'hard' end to the sentence (with a full stop) or a 'soft' ending (with a semicolon). See here:

Learning how to use colons and semicolons correctly can reduce the need for a large number of commas. (Incidentally, you've used a semicolon incorrectly in your first sentence; it should be a colon).
There are loads of online guides to using commas. This is one of the simpler ones:

PS: English is an evolving language. My school teachers would have been maddened by my use of a conjunction ('but') at the start of a sentence, above. However it now seems to be acceptable, even in 'serious' publications. So, as long as your writing can be understood, I wouldn't worry too much about the finer points of the language ;-)
