How to Create Setup project with default Sql Server Installer

Question

Hi Every body:
I have develop "Inventory Management System" for my clients. in the system i have use complete .NET programming and functionality with Crystal Reporting, Its Database is "MS SQL 2008".

My software installation in any windows pc required .net framework 2.0, and for software database, it required complete MS SQL SERVER 2008 or 2005.

According to the copyright. i can provide to the client .net framework setup which directly download from Microsoft. but i don't provide them "MS SQL 2008" setup, CD or keys OR dvd.

complete SQL SERVER setup installation is such a useless thing to do in clients PCs and i don't recommend this solution for my software to my client.

I Need a solution about this problem. Is there any way that i can create MS SQL Database to clients PC without installing Complete SQL SERVER ?

Please advise me any of hard easy third party tool which done this work in efficiently way !

Sorry if i posted this in the wrong forum. please move this into its proper forum.
