No .sql file

Hi everyone,

This might sound stupid but I just need to be sure. A developer I paid gave me heaps of files days ago for my project.  When I looked around the .php files, CodeIgniter came up so I joined this forum to make sure. When I asked few developers to upload for me, they said there was no database file (.sql) for them to upload.

I asked for the .sql or database file, all he gave me was this.

1. Import database
2. Database in folder database
3. Config database and folder:
    Open file index.php
    - Database: Line: 14, 15, 16, 17
    - Folder: Line 6.

4. chmod: 777 folder "uploads" and folder "cache_timthumb"

When I gave these instructions to 5 developers, all of them said "There was no .sql file" or "Is this a joke?".

I'm not sure if I'm asking the right question here. I checked around the whole file the developer gave me and there was no .sql file at all.
Is it a must to have the .sql file? Or is there a way to import the .sql file using the instructions he gave me? Or am I being played by this developer because he's been stalling to give me answers or a demo for a week now.
