POS and inventory system with Codeingniter

General information for the website: POS and inventory web system
Kind of development: New website from scratch
Description of every page/module: Admin module
Reporting module
Inventory module
POS module
Description of requirements/features: POS and inventory system
Extra notes: I have an POS and inventory software developed in VB.NET which I would like to replicate into a web system using codeigniter, bootstrap and mysql, so basically the work would be develop the same software, for which I will provide you all the screens, functionalities and MS ACCESS database (all tables).

The design should be very simple and minimalistic using Bootstrap 3, probably very similar as peopleperhour site.

UPDATE ** : Should be very similar to this http://spos.tecdiary.org/ (admin@tecdiary.com / 12345678) but much simpler in design and settings and using codeigniter.
