EPR/WEEE Data extraction

I require ever quarter annually data extraction and consolidation for WEEE data and submission and every 6 months data extraction and consolidation, you will be extracting data from spreadsheets and reports to consolidate in to returns. the data is small and easy to extract in to the final forms which produce numbers that i need to put in to a web based system.
the rate for this will be £30 for the quarterly so x 4 and the EPR data extraction is every 6 months so x 2 £50 per year.
Happy to provide a few samples of the data to be used for extraction and the forms the data is to be placed, payment will be invoiced after each return is completed?
