Create Math questions for grades4,5,6 and 7.

I am looking for some person who is interested in creating maths questions for grades 3, 4 , 5 and 6. I shall provide sample questions and the freelancer has to create similar questions keeping concept same. For example for my sample question " If Maria has 27 candies and she ate 3 of them, then what fraction of her candy did she eat ?", the question my freelancer may create "If David ate ( 1/6)th of the total 54 chocolates he had, then how many chocolates he is left with ?" What I mean that you need to create questions without deviation of the basic concept asked in my sample question. The questions with four options for each question(correct option in bold) are to be neatly typed in msword format. All the questions shall be reviewed. The interested freelancer may contact me. I shall be sending few sample questions before finalizing the contract.
