Stripe integration for a Python webapp

The person who originally designed/developed a Python based app cannot grant support anymore, so we look for any possible substitution, both in terms of ordinary webapp evolutionary maintenance and with regards to some impending interventions, such as little tweaks (simple text changes, an additional field required for user registration, and things like those) and the main task, which consist on integrating the user registration process with an already existent Stripe account, for allowing real time payment during signup. The complete and detailed workflow, with project requirements and fill technical specs would be provided via reserved communication channels. Also VPS' root password would be provided as well (together with both Stripe and webapp's admin and test user credentials). Of course we look for someone who is Python/Gunicorn skilled.
