Hi.
I work as a web application developer in Indonesia. I am very familiar with website designs, HTML, and CSS despite my status here as a new freelancer. I have seen your current website, and i'm sorry if i am being harsh, but it is a tad bit old fashioned :) And from the basic guidelines of responsive mobile design, it is not suitable. There needs to be a major reconstruction of the basic layout, thus changing the design altogether would be the best approach in my opinion.
If you are interested, i can provide you with a sample design, decide if you like it or hate it and feel free to contact me for further discussions regarding terms, fees and duration of the project.
I would love the opportunity to work with you.
Cheers :)
