Quality data for sales

I am looking for some clean quality data for companies that I can contact for collaborative opportunities. I am an interior designer and home stager and looking to work with architects and builders to offer mutual referrals to each other for work.

Identify companies for me that offer the following services:
Architectural design services
Loft conversions
Extensions
Residential developments
Building and construction services
Renovations
New Builds

Size of company
Company shouldn’t be too large so roughly 20 and under employees
Location
The focus is on Hampshire and Dorset, specifically SO and BH postcodes
Contacts
Individual contact name of the business owner/director/managing director/Chief Executive Officer/Chief Operating Officer/ architect or builder
Information required
• Name of Company
• Nature of business
• Number of employees
• Full Company postal address
• Name of individual
• Job title
• Specific named email address (i.e. joe.bloggs@company.com and not hello@, or info@ etc.)
• Direct dial phone number for the individual or their work mobile number
• Website address
• Instagram or facebook address

Please be clear in your proposal about what you can and can’t provide.

An estimate of how long it will take to provide the information would also be appreciated.

Any sample work provided should be relevant and demonstrate ability to provide the information requested
