I need a person skilled in PHP programming and calculations to make a few online calculators based on an Excel sheet with calculations.
There will be around 6 calculators and in total around 33 Input fields and 21 Output fields.
The calculations are based on (+ - * / and in 6 instances its calculating percentages. (%)
The Calculators are to be made with PHP and set up in very light css+html with the css in an external stylesheet.
We will skin the calculators later outselves.
The Calculators will be provided as an excel file, where you can see the exact relation between the input and output fields, together with already set up examples of how it is supposed to work.
Only bid on this job if you have good experience in making calculations in PHP.
Please send or link-to an example of earlier made calculators/calculations in PHP.
