Data collection of competitors prices

Good day,

We want to collect competitors prices every day and store them in a SQL database.

Data will come from a variety of sources:
- Webpages
- Excel files
- PDF files
- ...

There are aprox. 200 competitors, of which about 20 are relevant.
We aspire to have as many as possible and economically worth it.

IMPORTANT:
PLEASE BID YOUR QUOTE FOR A FEE PER YEAR.
We ask for a fixed quotation per year in exchange of your service to keep their products and prices every day updated in our database.

Looking forward to your bids.

EXAMPLE 1

- first product has 1 single price €/kWh, and 2 prices €/kW/día
- second product has 3 prices €/kWh, and 2 prices €/kW/día

All these numbers must be stored, together with attributes like: name of the product (Octopus Relax), pricing type (fixed single price), etc.
