This sounds like an interesting project.
I think you could try to get hold of documents from banks. Some of them have information about their services in English. If this isn’t possible in your country, try writing to the major British banks or looking on their websites. You might also be able to download information from these sites.
The information in these documents would lend themselves to the sort of activities you are talking about. Students could fill in tables that compare the bank accounts offered by various banks.
You could also try to get hold of annual reports from certain large companies. These usually contain graphs, tables and charts and texts that explain them. You could use just the text and ask students to fill in the tables.
You could also look at the websites of newspapers and magazines. For some of these you need to be a subscriber; but you might find sites that give news for free.
