Graphic Designer Quote - New iPhone App

We are currently designing a new and exciting information/statistical based iPhone App and are wondering how much it would cost to get the following produced by a:

- Professional Designer
- Student Designer

The work that would need to be completed would be:

- All Apple related icons, logos, tabs etc
- Launch/start-up screen
- Company/app related logos
- Background design and graphical based tweaks throughout the app

We are new to the app development world and so do not wish to offend anybody by specifying an unrealistic budget; basically we have no idea! This is the main reason why we are asking for quotes.

We are initially looking for just the graphic development stage as we are completing the building of the beta version at the moment. However if the app takes off (like we hope) then we would eventually be looking to hire.

We would be grateful if you could message your quotes to our inbox, along with links to any work which you may have already completed. And we will contact you as soon as possible. If you don't have any other experience do not worry as we would still be interested in quotes to gain knowledge of how much we will need to budget.

Many thanks,
