If you want a crappy looking job. You get what you pay for. Also, for a job like that, getting 3 quotes will take more time than the actual job. Get a referral from somebody who knows what they are talking about, and go with it! Geez, it's a $250 job at most, if they are licensed.
Excellent advice all the way around.
I thus retract my ridiculous statement about going with the cheapest quote! ;-)
