Quick Mod for Open Cart MVC Project

I am looking for a developer that's experienced with OpenCart and MVC development. This project should take you no more than 2-3hrs max. Please bid reasonably. This is not a complicated project. You'll simply be adding a custom message that only appears for a specific category if enabled through the [login to view URL] file. The message is based on cart total. About the project: Our store sells gift cards, and we're offering a promotion for every $100 in gift cards added to their cart, we're giving the buyer a $20 gift certificate. So if they buy $200 if gift certificates, they'll get show a message telling them they are getting $40 in bonus gift cards. i.e. if they buy $500 in gift certificates we will display a message telling them they are getting $100 in bonus cards. ( See attached image for the example ) The shopping cart doesn't have to do anything special, just display the custom dynamic notice. We've written this feature many years ago, but lost it during an upgrade. You can use our example images and PHP examples to quickly understand what we need! See my attached images for an example. $bonusCard = 20*(int)($totalAmt/100.); if(BONUS_CARD_ENABLE && $bonusCard > 0){ ?> Requirements: Add a custom dynamic message on the: product page, cart, order and confirm pages and in the customer emailed order details. See my attached images for examples.. The message will need to be configurable to target a unique category ID through the [login to view URL] file. We don't want this message to appear for all products, just a specific category and all products purchased under that category. The configuration should also include: if(date("Y-m-d") <= "2018-12-31"){ define('BONUS_CARD_ENABLE', 1); }else{ define('BONUS_CARD_ENABLE', 0); } Here are the message examples: ( See images for examples too ) Product Page Message when enabled and total is $100+ : $20 Bonus Card for every $100 gift card purchased will display on your final receipt after check out! Cart Message when enabled and total is $100+ : <?php } $bonusCard = 20*(int)($totalAmt/100.); if(BONUS_CARD_ENABLE && $bonusCard > 0){ ?> <tr> <td class="right"><b>Bonus Card:</b></td> <td class="right">$<?= $bonusCard?></td> </tr> <tr> <td colspan=2 class="right"><i>Your bonus voucher<?= $bonusCard == 20 ? "": "s" ?> will be mailed along with gift cards</td> </tr> <?php } ?> Order Page Message when enabled and total is $100+ : $bonusCard = 20*(int)($totalAmt/100.); Your bonus vouchers will be mailed along with gift cards. Order Email Message when enabled and total is $100+ : $bonusCard = 20*(int)($totalAmt/100.); Your bonus vouchers will be mailed along with gift cards. Looking for someone who can start now and finish within 2-3 hours. Do you understand what I need? If so, lets talk!
