Opencart Customization

Hi Everyone,

I have three task for an opencart website that needs to be done asap:

1) Addition of Tax/VAT Number Field on registration form and making sure that it does charge VAT for EU Zone during checkout.

2) Custom Purchased report with respect to product names.

3) Addition of Two more fields(Do you need a catalog & How did you hear about us) on registration form with email alert being sent to all admins, upon successful registration. At the moment the system does sends email with registration data, but have to make sure that these custom fields are also added on to that email.(I already have a module to add custom fields, can pass it successful bidder for customizing it to add other fields).

Due to workload, am outsourcing these task and hence expect quick turnaround time. (the built of opencart is version 1.5.3 and has vqmod as well)

Pls do provide examples of last three opencart ecommerce work that you have done.
