Assistance with building my Wordpress education site - Import theme, tweak appearance

General information for the website: Course selling
Description of requirements/features: I am building a wordpress based course website from the eduma theme. I know some wordpress but need assistance with certain tasks during the build. Including theme installation, demo import, theme tweaking and customization. Communicate with theme support when needed.
Then adding content, removing old demo content, sorting any bugs etc
Ongoing hourly work with adhoc tasks when required - adding new content, resolving problems, changing layout.
I'll supply all content, images, wording etc.
Probably 5 hours initial work then the odd hour here and there - hopefully indefinitely as the site grows.
I'm looking for someone I can text/email with a task and they can sort it for me and bill accordingly.
Obviously a good knowledge of wordpress is essential including theme tweaks.
UK based would be preferred.
Thanks.
