Imitation of an existing Customer Reward Points System

We want to develop a Customer Loyalty Management System, also called Customer Reward Points System. Since there are already many systems available in this category, the functionalists are already very well known. We want our system to be similar to one of the existing ones. For example: [login to view URL], [login to view URL], [login to view URL]; and [login to view URL], etc. This system includes: 1) a centralized processing server for reward points transactions, provided as SaaS; 2) a centralized CRM and user management interface, provided as a web-based application; 3) a POS, provided as an iOS and/or Android App; 4) a Portal website. We prefer that you have worked on similar projects before, and you own the source code. In this case, please provide: demos of your previous projects (please directly indicate the relevant part. If the relevant functionality is not shown, it is not a demo), and a summary of your implementation plan, and a brief introduction to you and your team, and a quote of your price. If you do not have any experience on this domain, and you have start programming from scratch, please study this domain, then provide: a summary of your understanding after summary, and what opensource project you think you can start with, and a brief introduction to you and your team, and a quote of your price. Ignore the highest and lowest bids that I entered, provide your own quote on price please.
