I worked alone and I spent approx. 15 hours on the analysis and documentation. Based on an average of 1900 hours of work per year the salary costs add up to 15/1900*70,000 = $553 My experience in programming: 15 years (incl. university) My experience in system administration: 11 years (mostly part time) My experience in security: 4 years full time as a security consultant, before that, 6 years part time as a system/ network administrator. To reinstall a RH6.2 default server 1-2 hours might be needed depending on the complexity of the hardware and the configuration, so total labor costs should be around $600.
