I am looking for a Joomla expert who can help me create an online global marketplace. We're using Joomla 3.4.3 and we've bought the theme is Vina Sagitta ([login to view URL]). References: Aiming for the look and feel of ([login to view URL]), Layout similar to ([login to view URL]) and this is an example marketplace that is in the same field ([login to view URL]). Most of the functionality is already provided by our plugin/extension ([login to view URL]) so majority of the features will be implemented using Joobi. I need to emphasize that we need the developer to know joobi inside out since that extension will be handling 90% of the functionality of the website. The deadline for this project is 10th Sept'2015, so the sooner we start the better. Although, this will be more on the lines of consulting since we already have two employees working on it and assistance will be provided. We will consider re-hiring from time-to-time if the job done meets our expectations. AGAIN, the developer will not have to create the whole website, he will only have to initiate tasks and guide a team to finish them.
