Masternode set up are not difficulty. There is a learning curve, but with the hundreds of similar guides, it would do well to figure it out.
Some of the hosting services like Apollon or GIN -- the cost for shared node is ~$3/mo. Vultr, Digital Ocean, etc is $5/mo usually for IPv4 VPS. Unless you're planning on squeezing in more than one masternode (if multiple ports are allowed), then you can save money by loading 3 masternodes on one VPS.
Personally, I won't ever support GUNCOIN again. The Telegram staff was completely rude (more like trollish). I sold off all my GUNCOIN.
Sorry to hear that. I am not aware of any issues in Telegram (I'm not staff) and I don't use Telegram actually.
You do have to look at the fundamentals of the coin though.
As for the VPS, you can get cheaper ones at $1 / month, but the reliability of those might a little lower, it just means you have to watch your node. Or you can run it at home if Guncoin masternodes are allowed to use a Tor (.onion) address.
