If I Understand correctly you want the exact same thing as the links you have provided, all I have to do is "copy/paste"? If so, that is rather easy and can be done in no time.
If not, It is still easy but can take longer (Always provided within 3 days of course)
As stated in my description, I can make pretty much make everything happen!
As a former Ghost Producer I have a wide range of genre that I can produce/compose, your demand is one of those!
The first day is the composition process, make everything right, the selection of instruments, the BPM, the theme and as you stated the melody. I use Bitwig Studio as DAW and various VSTs and Kontakt Libraries to enhance the realistic touch.
The second day is the mastering/mixing part of the job, I want you to have the best experience so that your customers can have one too. For this I use The Izotope Ozone and Neutro plugins.
The third day is the polishing day, I make sure that everything is at the right place so we get no surprises!
Hope to work together!
