Greetings, sir. I believe that I could be of great assistance to you on your project! I am a professional vocalist, guitarist, lyricist and a sound engineer with more than 10 years of experience in all of those fields.
You may check out my portfolio for song samples and my style of work!
I generally specialize in rock / metal / grunge music, so I believe that I could easily find my way around within this song. I also believe that I could finish it by tomorrow for sure, because I am free these two days.
I would just need all the files and, of course, your opinion on how it should sound and what do you expect from it, so I could know in which direction should I go with the track.
If you're interested in all of this, feel free to contact me here for further discussion, I am eager to work with you on this one!
Best regards, Bojan
