Ultimate Beginners guide to Deploy new hardware

Hi,
Don't want to start with the boring stuff, it's below.
I have a FortiGate FG-120G-BDL-950-12 with FC-10-F120G-131-02-12 what will replace a NSE-3000 (only) all other switches AP's remain Cambium.
Is there a comprehensive detailed design, implementation guide available what is fairly recent and up to date.


Recently tasked to replace a NSE-3000 router with something capable of BGP and have at least 3 SFP+ port, it was a long and slow process navigating through the sales team to acquire the correct hardware and licensing for it as they just wanted to sale the most expensive product they had in the catalogue  :rolling_on_the_floor_laughing:
I have no experience deploying Fortinet product but have managing 3x F40 & F60 for over a year,  most of my knowledge of FortiGate product is from experimenting, self paced learning portal and web sources and their paid support service.

I have heard in one of my conversation with the sales team from FN that there is implementation help available and or the support team is able to guide me through the initial implementation task but now that the product arrived and I have the license it's unsure if we got that service...

Is there support available here ? It will be a self paced implementation :D I have hardware for 2 weeks to myself (about) before reset it and install it in production env.
Anyone with the expertise, skills to teach and the time who can help me with this are welcome.

Lets start with this..

Thanks everyone.
