I am looking for a good Programmer to make cost estimate program for my website.
This is a site that allows individuals to build their house by themselves.
Now, I want to propose to them to calculate all the materials they will need to build their house and the price that will cost them to purchase.
The script will estimates quantity of materials and prices according to some specifications.
For example, how many bricks or blocks depending on the height, width and length of the walls, not to forget to remove the spaces for the location of doors and windows, and what is the cost of purchase of these materials.
Or, the volume of concrete, what will they need materials by materials (cement, sand, gravel, water) and what it will cost.
I want a simple interface such as the visitor will just have to fill in boxes (eg choice of materials "cinderblock - brick-etc", length, width, height; empty location of doors and windows) and the system will calculate everything.
The same for the rest (concrete, tile roofing, etc.).
I also want to be able to enter datas, add or remove some when necessary, when prices of materials are changing or when new materials arrives into the market.
This is a brief explanation of the project. I will go further with one who will make me the best and reasonable proposal.
It is a series of calculators, but it assumes that you also have an excellent knowledge of databases.
All this has to be supplied in documented source code so that I can upload it and host it on my server.
Everything can be subject to discussion.
I hope this first explanation is clear enough and I await your reasonable proposals.
