Hi
I'll keep this short since you didn't ask for it.
I built a desktop tool called CompanyScout that finds businesses by trade and location then pulls their email addresses and contact pages. You can search something like "marketing companies in Gauteng" get a list with names phones addresses and websites and export it to CSV. Searching and exporting are free and there's no account needed to try it.
You only pay if you want the app to send the emails or submit contact forms for you 窶 that part is $27 a month.
It runs on your own PC so the data stays with you rather than sitting on someone else's server. If it's not useful the free part costs you nothing but the download.

If you'd rather not hear from me reply with "no" and I won't follow up.
Thanks for your time The team at FreeB2BData
