looking to get a trademark to join the brand registry… what’s the cheapest option?

hello everyone! i’m a new seller on handmade amazon. i’d like to unlock all of the benefits using brand registry but the first person i contacted using the IP accelerator quoted $1250. i was hoping for something on the cheaper side, as i sell $6 products and this is only a side job. plus i don’t know if amazon is even going to work out. (i sell handmade bar soaps and bath products)

any suggestions or tips are wildly appreciated. thanks in advance!
