Build an online alloy calculator

<1st step> 1. it is to be built for mobile page. (You can check the sample site here : [login to view URL]) 2. domain and hosting will be arranged by us. (Most probably as a mobile page of [login to view URL] which is a simple shopping mall) 3. database: MySQL DB. 4. whole source should to be uploaded to the hosting by yourself.(we may help for this work.) 5. After uploading it must work as a web site without trouble 6. whole source should be provided as a file in order for ourselves to rectify whenever necessary. 7. alloy calculation process a. enter basic values at Admin page.(login is necessary to enter Admin page.) b. each alloy page automatically shows its values by simple formula calculation. c. if alloy values are arbitrarily amended by users themselves and the button of “calculate my data” is clicked, then “scrap value” is to be recalculated for the users themselves. d. In the administration page, when “save as history” is clicked, each value is to be stored in database. Up to here for this time. Please quote your reasonable price. <2nd step> 8. Future work: this will be done after 1st step of the above work is completed. - we would like to make many more alloy pages and history pages. - we would like to provide graphs with the data of history values.
