Make simple PHP or Javascript calculators - Weight/Fitness

Hi all, Thanks for reviewing my project. I need someone to help me make some simple online calulator and/or forms that I can use in my HTML websites. I need a 2 forms/calculators: 1. BMI Calculator EXAMPLE HERE: [login to view URL] FUNCTION: User types in their weight and height. Then the calculator gives them the BMI. FORMULA FOR CALCULATION: [login to view URL] ------------------------------------------------------------------------------------------- 2. Ideal Weight Calculator EXAMPLE HERE: [login to view URL] FUNCTION: User selects his gender(male or female) and his heights. Then the calculator gives him his ideal weight. FORMULA: [login to view URL] (You can see one for men and one for woman) ------------------------------------------------------------------------------------------- That's it for now, I will give the person in charge of this a simple HTML template where we will use the forms, or you can give us the functionality and we will take care of the rest. I would like to pay with PayPal or GAF, and my budget for this is $25-30. I will like to work with someone that I can rely on that will do a quality job and knows how to work in HTML/CSS to make sure the calculators look good in the final HTML template. I will provide this to the selected provider Thanks! Francisco
