Digital Store Addon for SNGINE

I Need a Digital Marketplace ADDON developed for SNGINE Social Network Script located here: [login to view URL] FEATURES NEEDED AS FOLLOWS: 1. COUPON & VOUCHER CODES: Ability to add coupon codes that can be entered on a redeem page for discounts (% or $) to pro packages and voucher codes that can be redeemed to give users X more points/wallet credit ... both should have expiration date and max # uses feature. Each code should only be usable once per account .. Refer to how Woocommerce discount coupons ([login to view URL]) and MyCred redemption vouchers ([login to view URL]) work for guidance. 2. POINT EARNERS: Currently Sngine supports earning points by posting, commenting and liking. Unfortunately, everywhere we've seen this tried, it encourages spammy content. Results were counter-productive .. SO IN ADDITION, We would like to add following point earners to reward quality over quantity: EARN POINTS for (A) receiving likes/reactions on posts/comments (B) sharing posts internally/externally (C) each time your posts are shared internally/externally (D) points for each new visitor as a result of sharing (E) and each referred signup as a result of sharing (F) and each signup that results in PRO upgrade (of any plan). This should effectively place username in each shared link and give every user the potential to receive both POINTS and AFFILIATE EARNINGS each time they share a post externally. We also need a "TIP" button on each post to allow users to tip post authors extra points at tipper's expense. 3. DIGITAL MARKETPLACE: Currently script supports classified marketplace which we need to rename as "Classifieds", which can then be duplicated to create a REAL digital "MARKETPLACE" addon by adding the following features: We need "BUY NOW" button and 3 more fields on product page: (1) Premium Content(ie Redeem Instructions) Textarea (wysiwig), (2) Optional Live Preview Link and (3) Optional Access Purchase Link (simple valid url) that will appear privately on product page to buyer only after user purchases with wallet-based credit. "BUY NOW" button to click w/confirm msgbox to confirm $$ purchase .. or replace with "ADD FUNDS" link button to Wallet ADD FUNDS page if balance is insufficient. Purchases need to be added to buyer's wallet transaction lists with link to product page (which should now show "ACCESS PURCHASE" link button and instructions after purchase), balance debited, and email receipt sent to both buyer/seller. Also REQUEST REFUND link button should appear for only (an admin-configurable) XX hours after purchase (hide if zero), which will automatically refund buyer and reverses transaction, negates premium access, and adds refund transaction for both buyer/seller with email receipts. We also need to Change In-Stock Status Option to (Available/Not Available), where only available products are purchase-able and listed/seen in search results. Unavailable products need to remain linked from buyer's transaction log so past buyers can still access their past purchases, while preventing any new purchases. Marketplace Products should be only offerable by BizPages (as author - similar to as "Offers" currently work), with a "Our Products" tab listed on BizPage profiles displaying Products of that BizPage (similar to Marketplace) .. and we need Sidebar widget on newsfeed showing X most recent products similar to: [login to view URL] IMPORTANT This addon script should be ERROR-FREE, come with Admin Backend page for config options, be secure against hacking, and not overwrite SNGINE original files, which would be overwritten by each new update from original author. Addon should only be developed as NEW PAGES, however a require/include will be allowed to load in new class library. All paid for codework and copyrights will be owned by payor.
