Is there a simple built-in way of converting NVARCHARs in the format "$1,000.00" and "($1,000.00)" to the numerical values 1000.00 and -1000.00 respectively?

I'm trying to do this in either SQL Server or SSIS.

Casting to MONEY gives me the error

"Cannot convert a char value to money. The char value has incorrect syntax.".

when attempting to cast the negative value, I'm assuming due to the parenthesis.
