I need 2 online calculators for my wordpress website.

Hi

I'd like to copy the following calculators for my wordpress website.

http://www.aren.co.ke/calculators/grosscalc.htm
http://www.aren.co.ke/calculators/payecalc.htm

I have an excel file which has the correct method and series of formulas for a similar calculation. One calculator is for gross to net pay and the other is net pay to gross pay. I will send the excel file to interested bidders.

I'd like to include these calculators on my wordpress website and if like this doing as soon as possible.
