Pricing is an important marketing tool and well understood by science in the late 80. Supermarkets were the driver for this research. Shoping at stores is sooo incredible designed, you wouldn't believe it, if they tell you everything they do.
If you search for pricing strategies online, you will find a lot of resources at universities of economy.
I've read a good and entertaining article about some basic pricing concepts at Joel Spolsky's blog. In the end he says, that you should charge only 0,99 for software unless its a bug tracker software ;)
Then, there have been an article series at UxMatters about Decision Architecture covering pricing as well and goes into psychogical details like anchoring effects,etc
A good summary of price effects at ConversionXL

To answer your question:
I can't understand why you think well educated people will feel affected by the price? I bet they will not even recognise it. And if so they wouldn't care.
First of all they look if your software will solve their specific needs. Next will probably be the reliability of your company and the probability of support. And the last is the price, unless you have a commodity software.
So, I would use some tricks for encourage them to buy your software. For me it isn't a dark pattern as tagged here, because the customers decision is made by features and company's reputation not by the price.
If you lie or make it look better regards the reputation (our customers are...) or features (feature only available first month...), that would be a dark pattern for me.
