Hello,
1st of all, I would like to tell you that its is not likely this solution can be built(with bug fixes and everything), within 1 month time. It will take 2 months, that is before the end of feburary.
Secondly, it would take 6,000(excluding commissions) for me to built it. There are few technicalities that need to be taken care of, and in addition to that, its Magento, which mean even installing a theme can get tough.
If you agree, i can send you break down as well as how i will implement it. We have made different modules of Magento for VAT, on top of standard VAT, as well as custom modules with details functionality. References can be provided on request.
