The only issue with something like that is that there is more than one way for someone to knock out a job when quoting it. There are a lot of little details that many people never take into consideration when vetting someone. Sometimes a quote from one contractor may be a bit higher, but it takes into account items that require foresight. Many contractors will bid a job low, and then include extras. Just keep this in mind. You want someone who will give you a comprehensive quote.
