django admin object level permission

I have a very simple Django admin site with 3 tables/models. I want to implement an Object Level permission in these tables. User can add/modified/delete/view ONLY their own record. User will not have superuser rights in the Django It's a quick project if you have encounter this before. I want ONLY bidder with EXACTLY the same experience on this that won't waste him/her more than a day to complete. I do not want any bidder who only "Think" he can do or make this as an experimental project. The project cost is $50-$100 depends on the speed you can complete this simple task. No bid more than $100 please (or if you can give a reason for higher bid, please specify). Happy bidding.
