Hiring consultants is like buying a new washing machine. In other words, you get what you pay for some times.
A couple of months ago, my washer and dryer were going out and I have been aware of this for some time. I was hesitant to purchase new appliances in attempts to prolong the outlay of funds as long as possible. In the meantime, I was dealing with a little leaking water, some bearings going out which caused the washer to be relatively loud (like a small jet engine) at times and a dryer that took a least two cycles to fully dry clothes. Of course, these appliances were of the lower end on quality, size and were fairly basic. Nothing fancy. Absolutely nothing wrong with that, in fact, I think I got more use of them than I thought possible at the time they were purchased.
