Best way forward for our product line

Hey guys, I’m just after a little advice.

we have a detailing product line and detailing outfit.
My question is, where do you think I should focus our attention, website revamp, social media ads, Google ads or seo.

we are growing steadily but I think we could scale up with the right strategy.

i have a home made wix website so I know that could be better at least. I’ve been offered a couple of websites but it’s hard to find someone you can trust to do the right job.

can I ask what you would do if you were me.

the website is http://www.Absolutevaleting.co.uk and the shop is at http://www.Absolutevaleting.co.uk/wax-shop

Thanks
