Usually the good price is the price you are comfortable with. But most of the time, this is a cheaper price than customer are willing to pay.
In any case you have the good behavior, put a price, give it a few months, if after a few months you feel like you want to increase it, do it, if you want to decrease it, do it and contact people who pay more.
And don't forget that if you want to target bigger customers, you can, but you will have to make them pay much more than currently, but you will also have to change a lot of things in the way you operate your company (you can have more info on my blog, link in my bio)
