Reader Request: Porta-Potty Recommendations

So this isn’t actually a reader request, but one for Jeremy and I: we’re getting ready to have a bunch of work done on the house and our contractor has suggested having a porta-potty for people to use.  I’m curious if any of you have found a good company for this – I guess we’d probably like to pay as little as possible but also make sure we get a company that does good work (which I guess means emptying it on schedule?).

If you can recommend a local porta-potty company, would you please comment on this post?  Thank you!
