Quick wordpress title change

Hello -

This is a very quick programming job. I just need the title on www.appnuts.co.uk changing from the site title to a log I've designed. I haven't got time to figure out the coding - but would like this project completed asap i.e. within 48 hours if possible.

Any questions, please ask. I have ftp and login details ready to send. May be lots of other jobs following.

Many thanks
