Shopify web developer

General information for the website: We are a startup baby wear brand using Shopify
Kind of development: Customization of existing website
Num. of web pages/modules: 1
Description of every page/module: For this job I am looking for a very simple tweak to the Jumpstart them in Shopify.

As our site is purely for information purposes at this point this small job will hopefully lead to much more extensive work on the site further down the line when we are ready to launch.
Description of requirements/features: All I require from this job is to make the default slideshow in the Jumpstart theme a full size slideshow. Frustratingly it is a reduced size at the moment. I would also like the ability to have text overlaid on the picture, just like in the Brooklyn template. I have included screenshots to show what I am talking about.
Extra notes: I am only willing to put up £15 for this very small job as it is clearly a minor code tweak and should a a 5 minute job for anyone worth their coding salt. BUT, there will be a major project down the line as we develop the site, so I am treating this minor job as an audition for a much larger job!
