B2B Contact List for Training Outreach

I am seeking a detailed and targeted B2B contact list of adult social care providers in South and West Wales for outreach regarding my Positive Behaviour Support training service.

Geographic focus, prioritised in this order:
Swansea and Carmarthenshire first,
then Neath Port Talbot and Rhondda Cynon Taf,
with Bridgend and Cardiff included if additional volume is required.

Service types required:
Adult supported living services
Residential services for adults with learning disabilities
Autism support services
Domiciliary care providers supporting complex needs

This list will be used for professional outreach to senior individuals likely to approve or commission staff training.

For each provider, I require:
Organisation name
Service type
Location
Senior decision-maker name and job title
Verified business email address
General service email if direct email is not available
Phone number
Website

Decision-maker roles to prioritise:
Director
Responsible Individual
Operations Manager
Training or Learning and Development Manager
Registered Manager where no senior leader is identifiable

Accuracy and relevance are more important than volume. Please confirm your approach to verifying business emails and provide samples of previous B2B list-building work if available.
