Build on existing Django code - small feature request

Dear All, Thank you for taking the time to review this project. I have Django code stored in Bitbucket for a very simple temporary website. I would like to have a 'subscribe' feature added where a visitor can subscribe/un-subscribe by entering their e-mail address. Key requirements: 1. Must be familiar with Git repositories via Github or Bitbucket and understand branching, commits etc. 2. Must be familiar with Linux environment. 3. Code must be clean and documented and should not use framework features that are deprecated in Django 1.8. Similarly, any packages readily available should not use features that are deprecated. 4. Understanding of Django Internationalisation. Features Spec: Subscribe feature (a django app) that will handle e-mail subscriptions from the home page via AJAX. The home page theme already provides appropriate form elements as part of the theme, so most of the front-end work is already done. The key part needed is the subscribe app that will carry out form handling without the need to refresh the page. Your quote: 1. Please provide a clear itemised quote for this task. Your quote must include a breakdown of what you intend to implement and whether or not you will be using existing Django packages that are readily available. 3. This is a low cost project, so please quote appropriately as this is one of many feature requests I will be submitting. 4. I am open to suggestions. If you have any ideas, please include them itemised in your quote. I am familiar with Django, Linux, Hosting, Domains etc, but have little time for development. Thanks in advance.
