WHMCS Report Customization - repost

Hi, Freelancers I would like to customize the Income Forecast report for WHMCS billing system as follows... Interested in the ability to select a past date. Then show the report starting from that date, while filtering out income from any orders/signups after that date. The effect would be to view the income forecast roughly as it appeared at any point in the past. If that is doable, we are also interested in taking things a step further, by adding a comparison to either the current date's forecast, or to a 2nd variable date projection. An ultimate, 3rd step, would be plotting the annual forecast total as it changes month to month over time between two dates. *Please bid only if you have experience with WHMCS billing system* My budget for this project is between $80-$120 Thanks for looking
