a shop should easily be able to do the front in less than 2 hours. The front is very very easy. I did my front springs in less than an hour with a lift and spring compressor.
I agree that the front is much easier than the rears.
Once you unbolt the strut assembly is very straight forward to take it out (unlike the rears where there are stuff in the way after you unbolt the shock-spring assembly).
Just make sure you have spring compressor handy before unbolting anything .
