Music track needs mixing

Hello, I need help from someone based in London to get a music track mixed. It's got marimbas, drum kit and vox. I need to re-record a few vocal lines (won't need more than 20mins to do so) and get the track tidied up and mixed. A bit of work has already been done on the track as we were recording - so there isn't a huge amount required. My total budget is £100 for this including the re-recording of the vox. If you're able to help get this done in the next week or two, please get in touch!
