THANKS Much everyone, good advice.
AND more importantly, I think I have it now.
adding one thing, a tablet with just Bitcoin info on it (blockchain, prices, etc)
Can wait to get my first BTC now!!
ooooooooooohhhh, ONE more question
WHICH exchange rate will customers expect to use? seems like everyone is quoting different, sometimes dramatically different, rates at the same time.
I plan on holding them as BTC for future btc purchases rather than turning to cash daily.
