I don't know much about the speakers or audio as far as the products or brands to buy, but I am confident that you could easily do it cleanly yourself.
My brother and I put my whole audio set up including subs into my Mustang a couple years ago and as long as you take your time you can do a very clean, quality job.
It is easy if you find the route you want to hide the wires. After that it is just running them and hooking them up.
So, my vote goes to do it yourself.
