I need a short animation made with sound

I want a short introduction video made for an upcoming project. the video would be very simple (I think)

deliverable in 1080p and 4k
start with blank, black screen
letters begin to fly in from all around the screen to form www.JSLawBooks.com
each letter as it falls into position makes a thud sound as it 'lands'
the letters should start off slowly and fall in faster from random places off-screen.
Once the website name is formed in the centre of the screen - it should pulse, growing in size and then going back again to its original state - as this happens a royalty/licence free sound of a wave crashing should play

once it has done that - it should hold for 3 seconds and that is the end

letters should be 3d effect in a bold, metallic silver and set against a black background
the sounds must be free to use with no royalties etc i would need the video in a range of standard formats
