Add an Dispute resolution page to our website

Hi We want an Arbitration page like what Freelancer has for resolving disputes added to our wordpress website. - Must be a clean modern design - User must pay a fee before proceeding - We do not need a payment gateway, all payments are paid in crypto currency. User manually transfers - User can post comments and upload files - We need a countdown timer as the dispute advances through the stages of arbitration - Page is to open in our website not on another tab - Arbitration is a 4 stage process like freelancers - Ability to award the dispute to either user or call it a draw. - User that wins will be refunded - defendant and complainant want you to pay (amount disputing like freelancer) this could also be a service etc
