Expensive, yes. Uncommon, no. There are many Japanese sword smiths working today and they are happy to forge a sword just for you.
I would recommend my friend Paul Martin. He lives in Tokyo and he knows all the ins and outs when it comes to commissioning a sword.. He can have anything you want done, done. Here is a link to a few of the sword smiths he currently works with, he can be contacted through his web site:

I am reluctant to provide Pauls' information as it seems apparent that you want a cheap sword.
Nothing he will provide you with will be cheap.
So, if you are only looking to spend say $2000,
please don't waste his time. A Katana, will cost you much more than that, at least three times that minimum and that is not in koshirae, but shirasaya only.
As far as the place you asked about, I can't answer. It appears they are in Japan, but they only sell Shinken and Iaito. These smiths are not licensed smiths which is why they only make practice blades, much like knife makers, they are a different group not under the ministry of culture.
The photos don't look bad, but photos can be deceiving. I have always found the old adage, "You get what you pay for" to be a wise saying.
