Hi,
I'm a professional sound engineer & a videographer owning an editing suite. Since you want to build something special for someone who you have feelings for, I would love to help you. I have a LOT of experience in making custom mixes, if you could share the list of songs, I'm pretty sure I can make a nice sounding mix which matches perfectly to the video.
I can edit the template and put your material into the template.
Regular price for such a project should be a lot higher, but since this is a personal project for your valentine, I offer you a big discounted price.
I'm almost always online, so please feel free to ask any questions that you might have in mind.
Regards,
Onur
