Custom development for rsforms pro joomla

The existing survey website is using rsforms extensions, but we need some improvements since rsforms dont save a session, that means when a client dont complete the questions the site will not save the answer and when the clien tries to continue the survey he should start from 0, this are the improvements: -The user should be able to enter the survey using an special code (different for each one), the website will ask for customer code to start survey. -The website should save the session and save completed answers, to allow the user to complete the survey later. -Every question should have a button to allow the user to record the answer instead of writing text, and should validate recorded voice, to ensure voice was detected. -A volume bars should appears ensuring voice is being detected -The joomla extension should be very easy to administrate via joomla backend. Right now we are using RSforms pro, so, the developer will modify existing survey system, with the requirements above Please start your offer using the word "READ" and your offer pirce, to know that you read this post.
