Do you outsource sales? If so how?

I used to outsource a part of the sale process for my cold emailing campaigns.
The process :

• defining the target (market, job title, company size, country...)
• collecting leads
• creating the email campaign (email template, scenario..)
• cold calling depending on the result of the email campaign

The part of collecting leads was outsourced to freelancers in China. We payed 0,5€ per lead (email address & other infos)

I think you should divide your sale process in order to know if you can really outsource everything, or just one part of it.

Curious, are you asking for your own business? or thinking of offering it as a service?

I would think it would be a hard thing to outsource. Is it the process or the sales person? Would think it would need to be mid sized orgs with a decent process already in place.
