I need an ecommerce website

I have a registered and active domain.

I just need a working and interactive website that can create customized meal plans for clients.

The clients sign up by putting their details such as name, email address, body measurements, current body weight, current body height, they select from a drop down menu the meals that they consume frequently, for breakfast, lunch and dinner. They also select the activities that they do most of the time and the duration of those activities.

At the back end, the program can calculate their BMI and also calculate their ideal weight.

From the data on the meals they constantly eat, the system can propose a meal plan with the activity that they prefer to do. We do not want to suggest meals that the client does not eat. We want to select from the data they have input as they sign up

The calories for the above 1 and 2 are also computed to say how many calories they will consume and expel with the food and exercises suggested

Once that is calculated, the client is prompted to pay for the meal plan, 7 day meal plan, that will project weekly weight loss if they follow the meal plan

They can be shown a snippet view of one day of the meal plan with their name to be confident in the system

Once they pay, the receipt is sent to their email address along with the meal plan.

You can look at www.eatthismuch.com to get an idea of the job that i want done.

I have the logos, the content, and the calculations all ready and will send them to the person that I give the job to.
