I have extensive experience with databases (Oracle, MS SQL, mySQL). As a developer I work with the following languages and technologies: C#(ASP.NET, Silverlight, WPF),PHP, Perl, HTML, CSS, Javascript, Please take a look at my portfolio.
About your project: it is a web application for a client (ASP.NET, HTML, JavaScript, CSS), because there is a mention about user registration.
Next, you write about the admin panel, this can be a windows app, but it could be a web app.
This work is not complicated, it is so, but unfortunately a lot of them, I therefore propose such a budget.
