Urgent aspx.NET database over MSSQL 2005 work *this weekend*

Very sorry for the short notice; I need someone available to work this weekend with the ability to develop a routine over an existing database in order to extract files which have been 'attached' to existing records (about 3000 records IIRC).
These are mainly PDFs, stored to SQL as binary, so I assume they will need extracting from the binary field and reconstructing into a new pdf file with the name set to the ID of the record from whence it came.
If you're able to come and work in E18, that'd be even better.
Once done we need to test on the local / test system here and upload to a remote system.
I'll need a Confidentiality agreement signed etc first, so that's another reason why local would be easier...
