It's a matter of what it's worth to you. What risks are you willing to take?
There are developers who may charge $700/hr, but you've chosen to go with a developer who charges $100/hr because that's what you need at this stage. If he made a mistake, it's not likely to cost you EVERYTHING to fix up. Somebody points out the bug / issue and you can hire him to sort it out and push out an update. Speak to a developer who works at a law firm ;)
Conversely, people device to go with a $700/hr lawyer because of their experience and reputation. You're paying for them to not make a mistake because it may just cost you EVERYTHING. It's not a mistake you can fix after it's found. Something wrong with your patent? Contract? Not something you can say 'oops, it's fixed now' to.
