Do not price on follower count. Price on what it costs you to deliver and what the usage is worth to them.

The first offer a brand makes is rarely their ceiling, and the number most new creators name is far below what the work costs them once travel, shooting and editing days are counted. Two things drive the real number: your cost to deliver, and the usage rights they are asking for. Follower count is the least important input.
Days of travel, days of shooting, days of editing, gear, fuel, permits. Put a day rate on your time. If the offer does not clear that, it is not a deal, it is a hobby with paperwork.
Making a video and licensing that video for the brand to run as a paid advertisement for a year are two different products. Organic post on your channel only is the baseline. Whitelisting, paid amplification, and use on their own channels each add to the number.
If they want you to not work with competitors for six months, that has a real cost because it removes future income. Price it or decline it. Never grant it for free, and never grant it in perpetuity.
Naming a number first is fine and it anchors the conversation. A one page card with tiers reads as professional and stops the endless back and forth.
What exactly is delivered, by when, where it can run, for how long, and when you get paid. Net thirty is normal. No contract means no recourse.
Product is not payment for a professional deliverable. It is fine when you genuinely wanted the item and the work is small. It is not fine as a substitute for a fee, and accepting it teaches the brand what you are worth.
Know your cost to deliver, price usage and exclusivity separately, send a rate card, and get deliverables and payment terms in writing. This is business information, not legal or financial advice, so have a professional look at any contract that matters.
