Hello.
As you already have the content, and I am very active Elementor Pro user in last few months, and I am able to create any kind of template 1:1 very quick, for your 12 pages, I will probably need less time than 4 days, but I count there are probably some additional parts, as forms etc. So, if you show me the example, I will act fast and reply with more detailed proposal.
Thanks.
Regards,
Neven
