WordPress Plugins & Small Site Changes Needed

Hello! So we are looking for a few WordPress plugins/stuff putting into our website; the basics are: - Tournament Page listing tournaments through the Toornament API ([login to view URL]) (more details below) - Credit System similar to SwagBucks or Skinsilo utilising TrialPay, Revenue Universe, AdGate Media, AdGem, RadiumOne, AdscendMedia & Fyber to payout credits. Rewards will include gift cards and sponsor gift cards. - Account Changes (more details below) - A [login to view URL] giveaway replica of the core features (e.g. subscribing to an account, following an account, performing actions for entries etc) - Small Store Edits (more details below) We are looking to have this done by the end of the week. MORE DETAILS: Tournament Page listing tournaments through the Toornament API: We want to utilise the toornament API to generate a tournament planner/organiser. Members can make their own tournaments on our tournament list or enter our weekly tournaments. There will be limitations to free account holders, those limitations are: - They can't host tournaments, but they can take part in them, while the other account tiers can host them. A few other details we would like: - Everything should be 100% customisable, including the tournament logos, places, prizes among other things. - In order to avoid scam tournaments, any and all tournaments with a cash prize above $10 will be placed on hold for review by an admin and will only be hosted once approved. - Each participant and host is required to be signed in to the website and completed the verification process Account Changes: The accounts currently are only signed up with email, we want to introduce a username requirement and tiers into the account. Upon going to the signup page, users will have to enter a username along with an email, the username can't be taken. There will be three different account types: Free, Prime and VIP, these will get access to exclusive items of our choosing from the control panel. We also want an introductory to do list added onto the user dashboard, where the users perform the following actions and upon completion of those actions they get rewarded a set credit amount that is customisable Small Store Edits: For the store, we want to add a gifting ability, which enables users to gift other users items purchased from the store, they can gift users by typing in the username of the person they'd like to gift it to on the cart page, or they can purchase it in the forms of gift cards and send it to the user via their username.
