Advance Payroll Calculator with Masters for Liferay

I need a Payroll calculator (attached are image of calculator as well its calculation formula). This payroll calculator has 3 types of Masters as described below (also available in attachment). Masters are consist of: a) Allowance ( 2 types: Fixed and Variable) b) Deductions c) Reimbursement The data of calculation and masters saved are temporary. The master and advance calculator would need to be in English and Malay. (The Malay Language can temporarily be a direct google translation) How Masters work: User logs into Liferay and creates masters to use with the advance calculator. It eases the calculations when the masters are preset by the user according to his need and reference created. When user logs out, all his master data / calculation data saved should be cleared/ erased. If user logs in again he would need to create the masters and do the calculation again. (this is created such as we want the user to only use the calculator for reference only) The delivery should be an easy install (1) War file as well (2) the files required to compile the war file itself, so we can update and recompile. This must work in Liferay version is 6.1.1 GA2 (Community Edition) and 6.1.0 CE Note: This Project is Very Urgent so its best taken by someone who is very experienced in Liferay and Payroll. Payment - Milestone. Duration to not exceed 7days. Attached is the Calculation Formula PDF, screenshot of sample Advance calculator, screenshot of the masters and list of tax category descriptions/ names for the dropdown field.
