Looking for a competent code writer to develop a custom debt reduction calculator to be used on multiple debt relief websites. The calculator will show various scenarios such as how long to pay off a balance if: 1) Making Only Minimum Payments 2) Making Minimum payments Plus a Designated % more than the minimum payment 2) Enrolling in a Credit Counseling Program 3) enrolling in a debt settlement program 4) paying off debt through a consolidation loan All logic and financial calculations will be provided. The calculator must display a chart with graphs. The calculator will be used in a WordPress site, using the Enfold Theme, running a child theme. Sample URl below (inserting * signs for prevention of search engine spidering and spam). T*I*M*B*E*R*L*I*N*E*F*I*N*A*N*C*I*A*L*.*C*O*M*/CALCULATOR <<<MUST BE FULLY RESPONSIVE ON MOBILE AND TABLET DEVICES>>> If you want to utilize a plugin for the calculations piece such as [login to view URL] and then write code for the graphs and charts based on teh output from the form calculator, that is an option I would consider. The important thing is that my designer can develop/edit/modify the output of the charts and graphs to match the current site design and change the output of the graphs and charts as me migrate the calculator to other sites.
