I will take the time to give a serious answer, even though this thread seems like it might be a parody of previous threads.
There are two main ways to get professional results. Either become a professional, or hire one. Ok, you don't really need to become a professional, but you need to put a serious investment into time and tools. You need to spend some time studying the subject. And you need to invest in quality tools, and allow the time to learn to use them. For many people, this learning process is fun. But if it sounds tedious, then hiring a professional will be the fastest, and CHEAPEST, way to get good results.
Also, the internet is full of bad advice, with lots of poor recommendations to "do it yourself." And installing your own sights is a good example of this problem. Dovetail sights often require hand fitting. And it takes a certain feel to know how tight is "right." Otherwise, they can either fall out, become jammed, or even damage the dovetail.
And yes, lots of times installing sights is pretty easy, and just a little more pressure from a sight pusher makes short work of it. But keep in mind that people who screwed something up don't boast about it on the internet. So many of the people saying that something is easy are a self selected group who just happened to get parts that fit well.
I am not saying that installing sights is difficult, or that you should not do it, but just think about the process. And I say this as someone who owns a dovetail file, but thinks very carefully about when to use it.
