Bubble io: Build additional features to the existing template

We have a telemedicine based template bought from bubble store, which does most of what we want. We need to do integrate few additional features: 1) Razorpay payment gateway integration. The website is based out of India. There is a plugin available on bubble store. If that fast-tracks the integration work, we are ready to buy it. 2) The payments are for 2 things - subscriptions and Booking Doctor. While the template provide all the booking features and payment pages, we need to create an additional page for subscription. We already have the subscription page built on Wix which we need to use a reference to replicate the same with payment integration with Razorpay. 3) Blog section integration - The admin and doctors have access to create and edit blogs while patients have access to read them. We have found a template on bubble store which does most of what we need. [login to view URL] While the UI of this template is not ok for us, if we can quickly implement using this template as reference, we are OK to buy it. 4) A landing page post Signup. A simple page used for customer convenience to redirect to various actions - book appointment, chat room, blogs and so on. We can share a reference image if needed. The action buttons are activated or deactivated based on subscription bought or if they are on trial. We would like someone who has already worked on Razorpay bubble integration, so that things happen quickly
