To best answer your question, it would be helpful to know the reasons why people own bitcoins. The way I see it, there are maybe 3 types of people in this babyconomy:
1. Speculators for real world wealth; buying or mining and holding BTC via exchange as a commodity, to sell back and be real world rich. They have no interest in the BTC economy personally, and are unlikely to spend BTC until they are satisfied they're rich.
2. Valuers; see the value in this type of economy, and are will to gain and trade BTC for other Goods and Services as they get them.
3. Businesses; also see the value in this type of economy, and will trade their Goods and Services for BTC, and pay their suppliers in BTC, to make their business run, while relying on btc/$ conversion as little as possible.
How many are in each group? At a mostly random guess, I would say maybe 98% speculators, 1.8% Valuers, and 0.2% businesses. The number of people who are actually using BTC to trade goods is probably quite small, and thus, your market here is probably tiny.
The BTC economy can survive excessive hoarding quite well because of its infinite splitting (unless I misunderstand that it can be), and people with 100,000 coins when people are buying and selling cars for 1mBTC will be stupidly rich, but once they've bought all they're going to buy, will either die and forget to pass on the encrypted data, or pass it on and it'll make its way through the system, and life will go on in either case.
The issue you are facing right now is that you're trying to sell something to a tiny market. If there are things which can only be bought via BTC, then BTC actually has a value over other currencies. The people buying your stuff already probably wouldn't care that they were paying in USD, or GBP, or EUR, or even BTC, as long as they were all the same "price", and if there's a choice, they'll pick the cheapest if know how to find it.
For example, if a day's work for a person earned them USD$200, GBP120 or 40microBTC, and they decided that they wanted what you were selling, and that paying "half a days' wage was an acceptable price", then they will be happy to pay USD$100, GBP60, or 20mBTC, whichever currency you asked them in, since the easiest way for a person to generally rate the price of something is on how difficult it is to re-earn that same dollar/pound/btc (their time factor). If it turned out that if the BTC price was only a quarter day's wages for the same thing, then they would most certainly do that, if they knew how.
You can safely ignore they hoarders, as they are not here to build an economy. You just offering the ability to accept BTCs is what matters. If you provide a service that another business can use, and they also trade in BTC, you will profit enormously, and that is, I believe, the only way real economies can be built.
Once a real economy is built, people will slowly be attracted to BTC as an economy if prices are always cheaper. Once it's established that prices are always cheaper via BTC (less overhead?), then people will come in droves, and BTCs will explode in usage, and you'd be glad to have been an early adopter. This is the point where banks get shitty and lobby to shut it all down.
