Promote a website

I need someone to help promote a website and the FB page connected with the site. I will share content of the website once we start communicating. The topic of the site can be considered controversial for some and supportive for others. So this can be challenging.

The website is for a business of mine and I need to bring traffic to the site and begin and increase sales for the site.

As well as looking for someone to take the task on, I will be looking for:

Competitive pricing.
Experience.
UK based due to my products only being shipped within the UK.
ATL and BTL Advertising. Mainly BTL.
Please send me links to show what work you have done in the past.
If you use social media to enhance promotion, then please send me links to all social media that you will use as well as any other sources.
If you have a website, please send a link to that as well.

If there is no response to your proposal, it means I'm researching anything you have sent or considering your proposal. I will reject instantly any proposal I believe that have not read this post or do not met what I am looking for.
