They have regular, express and rush services.
The price depends on the number of entries that you require.
Single entry 35 euros

I went to apply for the visa last month. The visa section was fully fully fully crowded. I arrived around 9:15am and there was a queue of 40 people outside the embassy!!
So you want to apply for same day service. Make sure you arrive at the embassy at 9:00 or earlier!
good luck
