Hello all,

I'm an advertising student working on a campaign to raise money for a charity that researches Autism.

Autistic people have problems communicating with others and I'd like that to be the focus of the campaign.

BT is a large sponsor of this charity. I'd like to propose a scheme whereby consumers can dial a prefix number before the regular 08 number when they call a company - half of the charges would be donated to this charity.

I need to have statistics on how much is spent in UK on 08 numbers. How long the average call is on an 08 number, the AVERAGE cost per minute.

Any advice on where I can go to find this information would be much appreciated!

Regards,

Will
