Hi, my name is Tom and I am a composer, I can produce a track just like the one in the video you referenced.
If you like, I will create a 1 minute version of the track (before you select your freelancer) and if you like it, we can work together and I will work on finishing the 5 minute track. This will take less than 5 days. If not, you may select another composer.
If you can include attribution, that would be great. I will write the music and give you the full licence for my bid, you can use the track in any video you like in the future for no further cost or royalties.
So, if you would like, send me a message and I will get you a sample made free of charge.
Thanks for your time, I look forward to hearing from you,
Tom.
