Looking for a developer to programmatically apply percentage calculations based on 1 of 3 different deal options,  ie Product 1, Product 2, Product 3 with 'monetary type custom fields' in the deals table to calculate diminishing returns over 3 fixed terms and automatically populate the custom fields so that we can copy and paste the inputs into a sales document. We have a few other similar related customisations also.  

I can provide more details, PDF and sheet of what need to do along with access to our account.
