For some context, industry standard for chat support is $2 to $2.50 per customer handled. The level of support you get with that is usually “Tier 1” which means they can answer questions like “How much does product X cost?” and “What are shipping fees?” and “Do you ship to X location?” and “Does it come in Red?”. What Serv.eth Support offers is closer to Tier 3 support, which means our staff understands the systems being used well enough to troubleshoot problems and gather technical support information required for effective escalations.
Something to keep in mind is that running a business often costs more than just the flat hourly rate of employees. Whether $3 is too high or not is certainly a subjective question and the answer is complex. I won’t assert that I am certain the pricing is correct. I will say though that it is not a get rich quick scheme for me at that rate. 
If someone can provide equal/better service for a lower price I definitely encourage them to submit a competing proposal! I created this business because I saw a dire need for basic Ethereum technical support across the ecosystem that was not being filled by anyone else. I would love it if someone filled that void, and it doesn’t have to be me.
