Hi I have a song i would like you to produce

My name is Shneur. I Have a rough demo song i will attach. I would like you to produced a full backing track in the style of Martin Garix. I will then record high quality vox here locally and then send them back to you to mix. 1)How much would that cost 2)how long would the production take? 3)How soon could you start? looking forward to hearing back from you.
