Facebook / Instagram Campaign to Sell Keyholder Services

I need someone that can help design, set-up and implement a facebook & instagram marketing campaign to sell keyholder services to holiday villa owners. We are a property management business based in North Mallorca. One key service is to look after the keys of holiday villas, check them regularly and make sure they are secure and maintained in good conditions when the owners aren't here. We are looking to attract more customers. Whilst the villas and apartments are here in Mallorca our audience is most likely in the UK or elsewhere in Northern Europe. They may be members of local info facebook groups but they may not. We want a campaign that promotes our services and the reasons an owner should appoint a manager (security, risk from storm damage etc) to these customers and drive leads and ultimately sales of keyholder services.

We need someone that can write the ads / copy (with our help), design them, set up and manage the campaigns.
