Nowadays, mining is difficult to earn reasonable profit. I think if you have professional knowledge, it is very easy to create your premium-rate Skype service call with Coinbase payment.
In many countries, it is very hard to apply for a premium-rate telephone number. You need to setup a corporation and build your telecom equipment. In this solution, you even don't need a server. Everyone can set up their Skype service within one hour.
Such as these examples

https://dl.dropboxusercontent.com/u/13076096/CatPawPaw.htmlAbove are only test samples, the Skype call is echo service. Anyone should be able to create their own service within one hour, as long as follow these steps:
1. Create a dropbox account and a coinbase account.
2. Design a page for introduction of service. And then put this page to Dropbox's public folder
3. Create a Skype button showing your online status in the introduction page.

7. Waiting call and earn bitcoin!!
The service provider could check the payment by order number told by customers. As a result, only the paid customers can access the service.
I think this should be the simplest way to create your own service to earn bitcoin. For promoting this idea, I will give away 0.05 BTC to first three persons creating useful Skype service pages. If I found another interesting service, I will also give BTC as reward. Leave your Bitcoin address.
