Developer Needed to Customize "Voice Recorder" and "Interactive Book""

It will be highly appreciated If you can do that or know someone who can.

This is a paid customization request.

I am interested in the following customizations in the "Interactive Book" and “Voice Recorder” components.

1- When showing the results after the user has finished the interactive book, the new requirement is to show 4 links, link title and URL to be customizable. 

2- In the Audio Recorder content type, when it is used in the interactive book, to have two options , the user can either write the answer or speak the answer then the voice gets transformed into text, before submitting the user can edit the resulting text then submit the answer. 

The user can get positive score points if he spoke or wrote certain keywords, also a score is given based on how long the answer is. 

3-  When showing the results after the user has finished the interactive book, show an extra graph result, the score of this graph to be based on the score of some selected questions plus or minus a random number.

For example, if the interactive book consists of 20 questions then the results of question 3,5 and 12 will be combined as one number (for ex the total is 38) then 38 plus a random number between 1-10 will be shown as a graph alongside the existing graphs in the final result page of the interactive book.

(Optional requirement), what would be the cost of 5 new graphs, all of them are exactly the same as explained in this point except that each result will be based on a different group of questions. for example graph 1 will be based on questions 3,5,12 and graph 2 will be based on questions 4,8,9 etc.
