Mini credit webpage creation (database, control panel, etc.)

We need to create a financial web to offer mini loans. For references you can see sites like vivus, creditomovil, kredito24, etc. It has to be multi language (at least English and Spanish). The operation is almost identical to these, incorporating databases and user accounts. In the initial screen you will be able to simulate a minicredit between 50 € and 500 € for 7 to 30 days. People register to apply for credit, first there will be an initial assessment form credit, if all goes well the account will be created and finally a platform created by "instantor" (external company) to make a study of the data entered customer. If the claim is rejected will be displayed along with a recommendation to apply for credit with one of our "partners". If the claim is accepted, the account is created in the system and will register the user, where you can view the data of credit. Will also need to confirm your email with a link. In the account may extend credit in 15 0 30 days by a button, for a good price. In the control panel, always the remaining days will appear for the actual credit, you will be able to download a PDF copy of the contract generated if the claim was accepted. This is a very simple explanation, we will indicate everything more deeply if the project is accepted but if you need more details, just enter a webpage like the ones named before, because its going to be almost identical.
