There really is more to whether you can/should do it yourself that you say. First, you have to do the homework before you know if your case is complicated or not. Then, you must have the attitude, aptitude, and motivation to do the homework, interpret accurately and answer accurately. Part of "aptitude" is the ability to "read carefully, and interpret literally". We se evidence of folks here every day who cannot or did not do even a C- job of any of that.
