KML data to a map in joomla component

We have a component- business directory in joomla, each business has a map. Now we have a map with a marker that points to the business. (We can provide online link) We want to add a route ( google map) that starts form a point , and ends to the business location using kml data. So instead of showing a map with a pin, we want to show a map with one pin of the starting point, the route and another pin of the business point. We want this to be added to the joomla component. Please keep in mind that we will reply only to proffesional bidders with previous examples of work. So send your portfolio if you have done a similar project.
