$750 - $1500

Project Description:

our client is running a couple of websites and he needs a new site for user registration and usage of this data for all his other sites. So that the user do not have to register on every single site from the beginning. By using the ID & password from the "registration site", user can login to his other sites. API needed for the existing sites.
We need a complete website where new user have to register (name, complete address etc.) first. With his unique ID and his password he´ll be able to use the other sites.
The given user data become verificated in 2 levels:
Level 1 is just an email verification. In Level 2 user need to upload any document like passport, drivers license and a valid payment method (creditcard or paypal or bank account). Given payment method will be used for paying fee. Admin has to check documents and payment method before enable.
Validation is for a period of time (f.e. 1 year). After that time validation expires if user did not validate emailaddress again (level 1).

Website needs a clear but good looking design. Multilingual (your part is english, we make the translations in the most used languages) and possibility to add languages. User needs his own userarea where he can add & edit his own data.
The database should store any kind of "writing/letters" because the users are international: US, Europe, India, China, Janan, Arabia etc. (and their given data should be finally same as written on passport for verification)

Site should be scaleable and easy to run on 2 or more servers (if needed) to handle a few million userdata.

Email templates for communication between site&user needed (multilingual).

Payment only via freelancer. 30% after design, flow and database structure, 40% after beta, uploaded on our server and testing, 30% when finished and bugs free.
We do not accept low bids which increase after awarding and we do not accept your freelancer fee as additional costs.

Thank you.
