Why would you pay $10,000 a year for advertisements when all you would really need would be your website and a YP listing (personally I don't use either one of those) If you are doing daily bar gigs with 3 or 4 people you already have the best advertisement in the world. Word of mouth from weddings are self perpetuating for business.
You spend $20.000 a year for equipment purchases! Wow you need to learn to operate a smaller system for most gigs and realize if you buy dependable equipment, learn how to operate it and take care of it you don't need to spend that much in 15 years! Learning how to purchase good used gear would help some too!
$24,000 a year for office expenses! You must have some office, I built my office/studio/storage building for less than $10,000 and yearly office expenses don't even close to that?
$15,000 for vehicle expenses per year, maybe if you include the payments on the new vehicles, insurance, fuel cost, tires etc. on all five work vehicles, but that is probably stretching it a bit.
Now you have to add in income from the 6 to 8 weekly bar gigs you will be doing besides the weekend gigs. You might be shooked at what a little prudent planning can do!
