I need bids for creating online calculators that need to be added to a health & fitness related web site. We need the following:

1. A calorie counter- something that could tell you the calories in various foods (we want it to have a lot of food options, but it can be generic and doesn't need to have brand name foods or products). Something similar to this: http://www.caloriescount.com/FoodCalculator.aspx

2. A fitness calculator- a set of tools that tells you how many calories you burn based on your weight, time spent doing that activity and the speed & time you work out). Something similar to the calculators found here: http://www.caloriesperhour.com/index_burn.php

If possible, I would like to see examples of similar calculators you have programmed previously. I will need a price estimate for the work, and the time frame for completion.
