From the command prompt:
bcp DBName.dbo.TableName OUT c:\TableName.bcp -N -T -Smydbserver\instance
Then, drop and re-create your tables (I don't think there's any simple way of doing this).
To get your data back,
bcp DBName.dbo.TableName IN c:\TableName.bcp -N -T -Smydbserver\instance
You will need to repeat this for each table. It will give you a binary copy of the data, which is then re-inserted. Just as long as each field is the same length as the old one, you shouldn't have any troubles re-inserting the data on a different schema.
