Hi,
I am interested in developing a "functional" clone of PayPal. The solution should have the architecture, security and scaleability that PayPal demands. This will be a single currency site ONLY, initial 100-1000 concurrent users. Architecture would be scaleable by adding additional servers etc.
Pl. quote separately for:
1. Architecture and scope concept paper
2. Development and testing
3. Hosting (on your or our servers separately)
4. Maintenance
