First 5 Sponsorship Offers

I've been wrestling with the idea of monetizing via sponsors on the newsletter.

On the one hand, I've had 5 people reach out to me asking if they could sponsor the newsletter + others asking to please feature their startup / other news on it.

On the other:

1. Not sure how I'd price it, I've heard anything from 0.05-0.1 euros per subscriber on specialized newsletters - but I want to make sure that if I charge people they are getting a lof of value out of it.

2. The spanish tax system is less than obvious to figure out, and charging for thiswould require spending some time figuring out how much money to put aside for next year. Its the type of stuff that really drains my energy, and I'm having so much fun writing and building this out + a full time job that I like - that I'm really not sure the amount I'd be charging for now is worth the trouble.

Decided for now. tokeep growing the business, and start accepting sponsorship deals once I get closer to 5-10K subs.

Any tips or recommendations on this highly appreciated!
