After getting power elite status,Envato interviewed Themefusion team.Their were two people behind Themefusion.
Luke and Mohammad both had contacted and start creating Avada and on August 2012,the template was published.In less than a year they achieve a massive sale hits.It sounds too strange that two unknown person contacted and created a template and publish it,really it needs a real confidence and your full time to make something inspirational.
According to Luke,it is better to get inspiration,but copying it the same is not a deal.If you want to achieve something you need to work and think differently.
It shows that if you want to do something,then keep on that and you can achieve that.If we talk about Avada,I can say it is a complete Wordpress template with tons and tons of different functions.
I use to tweak templates on Themeforest and I have an idea of a high class template.Avada is priced $45 which is a really less amount,because still there are multi purpose themes which got price of about $80.
Avada got more than 30 thousand sales and I give tribute to these two authors,as they worked too much hard and created something that other can't.
