I counted 31 shows in this run. Heather says she spent over 13,000 on the phones to prepare for it. That means the phones cost her $419.35 per show.
There were already existing hardwired lines, and existing equipment. She spent $13,000 on what exactly?
I have no idea why she doesn't just hire an I.T. person to help her, probably short of funds. But if she actually did burn through over $13,000 it would be much more cost effective to hire someone to show up and explain how the equipment works for a day or two.
