Hi Harpreet,
When you deploy your application on IIS, It will take identity of IIS user, not logged in user. From connection string it seems that your are using window authentication for SQL server but it is not possible from IIS.
So pass userid and password in connection string. It may resolve your problem.

You can add one. If you used Microsoft SQL Server Management Studio, open your SQLExpress database under the object explorer. Expand the Security option. Right click on Logins and enter a new login name. Choose SQL Server authentication, and give it a good password. If you are worried about the plain text in your config file, you can encrypt it using the aspNet_regiis see http://msdn.microsoft.com/en-us/library/zhhddkxy.aspx for usage.

Option 1:
Your keyword are: application pool identities
You need to set App Pool user an account have permission to create DB on SQL
http://www.iis.net/learn/manage/configuring-security/application-pool-identities

Option 2:
Give a try to remove "Initial Catalog=project;" from your connection string.
