Looking for Expert Opencart Developer - Custom Functions Needed

Hi, We're looking for someone who has at least 5 years of experience. We are looking to implement a personalized function to be added to the cart and the backend. We have a website built with these functions on an old platform. But we do not want to publicly display our website here. It's similar to a personalized card website. Where you input the personalized information in the different fields such as names, hobbies or likes and it'll show up in the image on the left with texts. Once the personalized text is done, it'll be saved in the backend for us to copy and paste to print. There are a few other smaller functions such as add on product pages after you add to cart and also, revise personalization function on the cart, Preview link on personalization options on product page, there maybe a couple more smaller functions. We have a few extensions installed as well: 1. Export/Import Tool (V3.11) for OpenCart 2.x 2. PersistentCart by iSenseLabs 3. Facebook Pixel Plugin 4. AbandonedCarts by iSenseLabs (OC 2.3.x) 5. C2 Multiupload files light OSMOD It's running on Opencart 2.3.0.2 with Journal 2 Theme. Please do not bid unless you are a very experience opencart coder. Budget is around $150.
