Completing a script and installing/configuring it in the hosting

Hello, First of all, I need to say, I can not make a guessing about the price. If you think you can do the followings please give your price offers. We can continue with details in the interview. During the interview, if it is needed, you can make adjustments to your prices. I have a script prepared by using Python, django, mysql and html. But this script is lacking in financial functions. I need to you to add the following functions: 1. Customers can buy credits and use these credits to buy services. 2. freelancer will provide their services and according to their work they will earn credits. Customers and freelancers have their basic profiles now. But we need to add these financial data to their profiles (for customers their spendings, list of jobs given to freelancers) and (for freelancers, their earnings, their works) so that they can keep track. And the system will make payments to freelancers every month for example. Other than this, I need a home page and 3-4 other pages, and some small design changes, like colors etc. I hope we can build a friendly and long term cooperation. Thank you
