I need custom options for 457 records on a M2 website updated

We have 457 products within https://www.brooksuspension.co.uk/steering-dampers/hyperpro?product_list_dir=desc&product_list_order=price that contain custom options for fitting kits which are a seperate SKU to the product itself.

In the below example:

https://www.brooksuspension.co.uk/steering-dampers/kawasaki-z-h2-hyperpro-rsc-steering-damper-20-23

DS-068*-NP1 is the SKU for the steering damper and in this instance the last 2 digits -1 are an identifier (as there are multiple simple products with the same SKU).

The product contains a a drop down custom option(s) for a fitting kit in Gold, with a displayed SKU (in the backend only) as MK-KA10-T010.

The product SKU price is up to date and the custom option SKU price isn't, we would like this updated and do not currently have capacity for it internally.

We of course have lots of this type of ongoing task so we would encourage building a long term relationship with a solution provider to cleanse and update our database as and when we need it.

The new price list is here https://docs.google.com/spreadsheets/d/1NJb3SXcWL1fQz_euUjurbOZBuXpSJ8CJ/edit#gid=1454136411
