Woo commerce customization

Hey I need help in customizing my woo Commerce store. I have made a few customizations and am now stuck, I want some expert to help fix the issue. I am looking for long term relationship. I would prefer individual over agency and task need to be done today. I will share more detail with the selected candidates. Please include your 3 best examples of customized woo-commerce store. To give an overview of task I need product price on product page to be updated on the basis of user option selection using ajax. I was able to change the price but now stuck on hooking the changed price to woo cart and order. Please write WOO at the start of your bid. Thanks
