Shopify coding work on banner

Hi need a micro project done in my Shopify site. ***If you are not available to get this done in an hour or under today, please to not bid on this project. It is time sensitive** Freelancer MUST be a shopify expert. I am looking to have an existing logo made larger and centered in the banner of my homepage. The links to my categories need to be placed below it. This will involve changing the coding and making the banner bigger. I also need the announcement bar made larger. This is a simple project for someone that knows Shopify coding and knows how to make this minor change. $20 is my budget MAX and I need it done in an hour or less.
