According to NameBio.com
The Domain serviceprojects.com sold for $1,300 back in Feb
I think that sets the bar nicely for a similar .com (.info, is obviously worth much less)
If you owned the .com version, you might be looking at mid xxx, however with the .info extension, I do believe that servicemaster.info would probably be pulling in low xx - the combination of words is just lacking. This is of course just an opinion, good luck.
