Aftermarket sight installation

[GHETTO BLASTER]

I've been thinking about replacing the white dot sights on my P95 with trijicon or some sort of night sights.I've never had any gunsmith work done and I was wondering about how much does it usually cost to have done?

***Although I don't have a P95 when I purchased my night sights for one of my firearms - the store I purchased them from charged me $20 to install them. I've purchased from other places that installed them for free but I purchased the gun and sights at the same time so they installed them while waiting for the MSP to get back to them with my ND.
