I’d start by posting more than once a week – that’s not enough to gain momentum or gain attention, especially since you don’t have an audience already. A content plan would go a long way here – yes, you can post what you’ve already mentioned…but there’s also a lot more. If you want to be doing commercials/print for everyday items, it needs to be easy to picture you using said items. Is there a particular niche of items you’re more interested in, or are you open to all types?

Hashtags are not spammy – I put mine in the first comment, alternate for each post, and use the max comments. They help algorithm, and you may gain new attention from them.

I don’t think you necessarily need a producer – but you do need a solid content plan that works for your goals + how much time you have.
