Invideo contacted me about a partnership

Hi Folks,
I run my business where I help produce podcasts. Invideo contacted me yesterday about a partnership stating:
We'd be interested in either writing an article for you or collaborating on link placement.
In exchange, I can offer you:

1. Free access to our studio tool
2. A backlink from our partner websites
3. Opportunities for paid partnerships

I just added an affiliate link for Ocoya on my blog articles last week so this was funny timing.

I also dipped my toe in Affilte Marketing and built another site.
I plan on either creating new links with GSA SER as I've read articles on here recommending over other ones like MoneyRobot etc.
or paying for a Domain Booster ( Ive used Linkdaddy before and I thought it worked well).

Any advice or tips on anything I've mention about my two websites I'd love to hear it.

Thanks
