Website prototype to be done in Sketch.app

I have a design for a website which has been done in Indesign and then a pdf.
Client has his own developer who has asked us to convert our design to the "sketch" app.

Either that or a layered Photoshop file.

I am looking for someone who is familiar with the Sketch software.
If you are please let me know what you hourly rate is and an approx time that you will be able to turn it around in. I imagine it would be a good days work.

Thanks
