Custom CRM / Private Agent Tracking Site

Hello, this is custom project that is going to be used in house only. This needs to be able to handle 100+ users and will need to be able to a minimum of 5 levels of connections and reporting with access being restricted by login. The system does need to support membership permission levels within multiple levels or groups for compensation including down line and lateral referral arrangements. The downline will aspect will include commissions like a downline referral system. Please quote on both single production, with maintenance, as well as please quote individual hourly rates. Please be as realistic in time and cost as posible. Thank you.
