Is there a market for this?

I'm posting here because I think MSP will have the answer or will have possibly turned down business from a customer that might be 'too small' for the MSPs lowest tiered plan.

I don't want to be an MSP, I really just want to target very small businesses that need network/wifi/security cameras and that's it (not all three, any combo is fine). I'm not interested in becoming an MSP, way too many things you have to deal with and think about.

That being said, my biggest issue is likely that the customer I'm looking for is already under contract with an MSP which handles the items I mentioned in addition to the rest of their IT needs or they are small enough of a business that the ISP all in one router works just fine for their needs.

For those that are actively in this space, is there a market for this type of service or am I looking for a needle in a haystack?

Thanks.
