Website horse apparel

Hi,
I need someone to help with some small extras in my new Shopify website. I build it myself but I m stuck with the following:

- change symbol of checkout in header
- add heart symbol for wish list at header
- change menu to mega menu (with picture)
- create the fooder as per given example to be copied
- adjust banner to mobile view

The theme I m using is dawn.

Thanks a lot for a a quotation.

Best
Anna
