I need the pricing in two InDesign pricelists updated

We require the pricing in our two furniture pricelists to be updated (one in GBP, one in EUR). I would expect it to take approx 25 hours for both. Accuracy in transferring pricing from excel documents to the InDesign file is very important. There will be no other graphic work within the document, just updating pricing. We need this delivered by 30th April and will be ready to start the project 18th April. There will be similar ongoing projects in the future if wanted. See sample pricelist page attached.
