Help us build a B2B digital sales funnel and then run & optimise it

We are a Helsinki Finland based digital business consulting company looking to build an online sales funnel to acquire clients internationally. We are starting off with LinkedIn and expanding to other channels later on. We have defined target group and personas and are finishing off a whitepaper to use as a lead magnet. Currently setting up landing pages for gathering emails and for converting those into meetings. Currently doing this ourselves but will need hands-on help with setting-up, optimising, copywriting, a/b testing and content production. The aim is to build a solid lead generation machine for our sales.
