Series of icons wanted for iPhone app

Education

We are developing an iPhone mapping app to help students at large universities find there way around campus.

We need a set of 21 icons designed to represent our different place categories. You don't need to submit all 21 icons at first, send a few examples and we'll comment on the style. The icons will be used in three main ways within the iPhone app - Lists - Map markers - Image placeholders (where no photo exists) The categories: - Lecture theatres - Buildings - Rooms - Female toilets - Male toilets - Disabled toilets - Coffee - Food - Bars - Uni services - Offices - Parking - Sport - Computers - Shops - ATMs - Accommodation - Landmarks - WiFi hotspots - Printing - Secret places Dimensions: - 400x400 pixels - Must look good at 40 x 40 pixels Transparency: The background of each icon must be transparent so any background image/gradient will show through. Colours: The icons are to be mainly black with orange highlights. We're not sure if we want a solid or gradient orange: - Solid orange: RGB(98, 48, 5) - Gradient: RGB(100,40,0) - RGB(97, 58, 11) Overall design: - We need all the icons to be simple because they need to be shown small sometimes. - Please view the iPhone image which shows the main menu of our app - we want the icons to work into this design. File formats (for the winning designs): - The finished designs should be separate uncompressed PNG images at a minimum. - Photoshop or vector files would be useful (depending on what program you use to create them).

Every design category has flexible pricing for all budgets.
