social media manager

We are an admin company with links to a funding bank.
We need to get customers who are looking for a credit line. The service we provide is that the customer needs to clear Credit/Debit card payments for his business, payments from Just Eat, Deliveroo, and Justeat are regarded by the bank as credit card transactions. The bank will calculate the amount they want to offer as a loan and offer this direct to the customer. All other admin-related things will be handled by the Lender (bank).

so we can do it with a person who can do the work for us on a monthly basis. We have authorization from the Bank to operate in the UK / USA / The Netherlands / Germany / Spain / Belgium / Poland.
We would like to start with the UK.

I am open to any suggestion.
