Pls dont award before discussing
I hope you are doing well in your business and wants to use the extensive feature of drupal into your website which will give you more flexibility, security, easy to manage the content etc..
The theme you have specified is chargable, so we need the theme to study it in details. Drupal also have the forest theme, but that theme may be chargable. So, we need that theme from you. If the similar theme is not found in drupal then custom theme has to be designed to keep in mind the design of the wordpress theme .
This theme has several features like drop down menu, social networking,position for advertisement etc. All the above features we can implement and also the other updates into the sites with respective modules of drupal and if required then custom module can be developed with some extra charges. We need also in details about the other updates like your brand.
The look and feel of the theme can also be modified like http://www.worldofwanderlust. If any other features you want to add into this theme then additional charges will be required. If you want, we can provide you the demonstration along with your content.
If you have any plan to implement shopping cart into the site we can do it using ubercart module and paypal payment gateway.
Generally we don't try to prove our credential in writing, because we believe on our work not in word. We have worked in so many technologies and have familiar to work in any new technologies.
Hope we wil
