Our starting point is that we, as experts in the field, carry out such a large part of the work: partly by obtaining tenders, partly by analysing the tenders and partly by implementing.
The only thing you can help with is to give us access to your telephony bills as well as the agreement with your current company.
Overall, the course takes 6-8 weeks, and you should expect to have to set aside 1-2 days depending on the scope and complexity.
