Telesales and appointment setting

We are a commercial cleaning company based in Nottingham looking to grow our client base. We want to appoint an outsourced telemarketer who can make cold calls for us with a view to setting appointments.
We will work together to set up a CRM sales funnel to keep track of our leads.
We do not have any data at present so need help sourcing data, we can advise what we are looking for in terms of location, business size etc.
I want somebody on going for the rest of this year and if successful will conitnue into 2025.
Rate stated is per week and we can discuss hours or call numbers you will be approx. able to make for this weekly budget.
