Design and Analysis of Algorithms (Parallel Algorithms)

I need help with a simple task regarding designing and Analysing Algorithms, (CRCW PRAM, EREW PRAM, time complexity, and sorting networks for multi-processor computers and switching networks). the task includes 4 parts that require writing and explaining the algorithm.
my budget for this task is 25$ and I need it in 4 days.
if you are an expert in this field and you will be able to do this task for me (within the budget) please message me to provide more details about the task.
Thank you
