Hi there,
My name is Darren Rea. I have ten years experience playing, writing and producing music and sounds and have experience working with high-grade recording, instrument and sound design software, allowing me also to work with a vast majority of instruments and "noises". As of last year, I have completed both the BaMus and BMus degrees from University College Cork within four years and received the Donal "Doc" Gleeson Award for performance during my time there.
Having experience myself designing games and apps, I understand the processes behind developing a functioning program and being accepted for this project, I will discuss length, tone, style, volume, etc etc (I know you've mentioned length below but just to know an exact time for fade outs and triggers), to make sure you get the exact result you are looking for.
Head over to my profile and check out "CCI" and "Gamelan Creep" from my portfolio. These samples both have elements that would fall perfectly into the "Sci-Fi" theme you are looking to obtain. Of course everything would be originally designed for you. I create unique and individual work for each client, meaning you get the exact result you want.
Just to mention, I cannot see how this project could go over the time mentioned above, however, if it does, there will be no additional charge from the above quote.
Hope to talk soon and thank you of your time.
Regards,
DMRea
