buliding mywebsite and building custom code that works directly in Wordpress via php

I need a web application developed. I hope that's the correct term to use... I'm looking create a section on my website where users can choose a number from 1-25 (voting system) from 4 different categories. They would be giving "ratings" on two different music tracks. Four categories, so a total of 100 points. {it's a creativity competition} Per "round" however, I want a total of 5 user ratings giving a total of 500 possible points. After 5 users have voted on the 4 categories, there would be a winner {it's a creativity competition}. Since it's a competition, there would be two playlists, and two music players (basically everything doubled). The playlists should be aggregated from, in this case, music producers who upload their music to be apart of the competition. The users select a track from "playlist a", then a track from "playlist b". They vote, and the playlist with the most points (therefore the producer who uploaded that particular track) wins. Actual money. There's more to it, but I want to see if thus far you would be able to create what I've described. Thanks in advance! (Wordpress is the base for my site. Hosting by Go Daddy) I'm waiting for someone that's fully confident in their skills and knows they can really complete this. I included two pictures that show the layout I'm going for. Of course there would be more pages to have all of the functionalities available to users. For instance, a logged in user page where they can see how much money they've made, and be able to make deposits/withdrawals, etc. Please note. This project is IN ADDITION to the rest of my website that's being worked on via Wordpress. After speaking to multiple people, I've gotten mixed answers as to whether or not it's even possible to implement into Wordpress. Please let me know your thoughts. Can you also set up a system for different types of custom user profiles? Custom meaning different templates and stipulations for various types of profiles? With the ability to control different pricing level? Furthermore, I need the data of the voting system to be able to be displayed in list. (As shown in the pictures.) Is all of this possible for you
