Moving products from Opencart to WordPress with Avada and woocommerce

I am upgrading a website https://www.myfirstrecord.co.uk/ from Opencart version 1.5.4 to Wordpress, using the Avada theme with WooCommerce plugin. The new website should retain all the existing products and have the full user purchase journey through to checkout with the following features:

- Online store with shopping cart
- Product categories and filters

If you have a look through the current website you can see the various purchase options and functionality like being able to choose an engraved plaque for an additional charge and if that is chosen then they will need to add the text for the plaque up to a max of 88 characters like this one https://www.myfirstrecord.co.uk/special-gift-framed-vinyl-single

I'm looking for someone with a strong background in website development, particularly in transitioning sites from Opencart to Wordpress, and using the Avada theme. Experience with WooCommerce is also a significant advantage.

I am not looking for someone to build the whole site but just get the products moved and the e-commerce side of things working.

I will then add in other content and style it but may well ask whoever takes on this part of the project to help with some other bits.
