If someone insists on the format you've posetd, i believe it is a job for lines of code rather than a simple PICture. . .
This is the first time i've seen a requirement that the minus sign and the $ had to be shown as -$ in the output. It might be worth the effort to get a buy-in from whatever manager/user on one of the standard output formats.
