Members Access

I have a website called [login to view URL] and I'm at a dead end. I've created and designed most of the website myself, including the cosmetics and even some coding. Now I am trying to create a membership access page on my website for paying members to have access to things for free which others cannot. I'd like to set up a recurring payment (monthly subscription) I have consulted many other experts and looked for help but most of the time they are either asking for far too much money or they recommend creating an entirely separate website but Im confident I could work around that. I'm just looking for someone to help me set this up, or would pay to do it themselves. So far I have narrowed it down to just one thing; The account page on shopify. They have an account page built into websites where you have the option to login and access your orders and track current placed orders. I want to customize that page with plugins and widgets from powr form builder and other tools I use but I think the only way to do that is by coding in and I'm no genius. The idea is to set up 2 gateways one being a pop up when a customer first visits the website which I have already set up, that will than forward them to the login page called "Members Access" and another gateway is the login page itself. Once the user logins and they don't have a membership, they will be brought to the landing platform where they are offered a 7 day trial access to the members only page. They than fill out personal information, etc. Than go to checkout and proceed to payment (paypal or card). Once they have done this they have access to the page. There are things I need to set up after this entire system has been set up and is working. Things like displaying the same products that were featured on the website, but with the members access they will become free on that page ONLY. Basically once they login on the page and have a valid membership they are brought to dashboard page, separate from the website but still on the website, with everything on it. But for now just setting up this system is my main priority. There are not allot of people who have done this on shopify, if any. So I understand there is a possibility that I will have to create a separate website entirely but I would like to avoid that. Please contact me if there is anything you can do.
