CSI keeps your cost down by keeping our overhead down. When you deal with us you are not paying for expensive office space. It looks good, but someone is paying for it, and that someone is you. As of May 1st, 2008 our hourly rate is $90.00. The result is the same: it just costs less.  Time is billed in quarter-hour increments and the minimum billing per visit is one-half hour. Rates for evenings and weekends are higher.
