I run an independant iPhone/iPod repair shop in Birmingham and would like to offer my services. PM if you would like more details.
Alternatively, like tiptopp said you could try the repair yourself if it something simple that has been damaged such as the LCD. If the glass is damaged it can be more of a task to replace.
Also, watch out for cheap parts on eBay that are copies and not OEM. I deal with both types of parts and can guarantee the quality is vastly different.
Some people, however, don't mind the copies and are more than happy for me to use them on their phones.
