I had previously used excel spreadsheets to monitor everything, and in reality, probably still could. 

Our economy became highly specialized, and in spite of the "high" cost of hiring professionals, a true Pro is worth his weight in gold.So here's what I consider a very practical suggestion...Sit down and DECIDE: How much do I want to earn per hour?  

The reviews on Google from locals that have actually used those particular companies would probably carry more weight.

It's actually the amount of weight it takes to indent a 4" piece of foam 25% (with a 12" disc weight).

Does it carry much weight?  

Another point of failure that has to be monitored.  

The lottery was set up as a weighted lottery.  

Have you ever looked into any kind of leak monitoring?

Although more expensive, I swear by Grohe (as do most plumbers worth their weight).

Obviously calculating income for your numbers is extremely important but not much weight is put into that for the appraisal.
