Urgent Online Mediation Required for Payment Dispute

I've been in a contractual relationship with Brett for the past seven months, working to expand his audience and revenue. Despite hitting significant milestones—like generating $33k from a single webinar—Brett has refused to pay the agreed-upon percentage. On top of that, he owes me $3k, which he initially claimed was tied up in Payoneer but later said he would only pay when the funds became available.

The situation has become increasingly frustrating, compounded by delays, a lack of transparency, and Brett's refusal to provide proof of transactions. These issues have caused me considerable stress over the past two months, leaving me in a precarious financial situation.

I'm seeking a skilled mediator who specializes in online negotiations, to help me recover the money I'm owed as swiftly as possible. I have a contract and communication records—mainly emails and text messages—that support my claims. This is my first experience with a mediation process, and I'm hoping for a swift and fair resolution.

Ideal Skills and Experience:
- Proven track record in online mediation
- Strong negotiation skills
- Experience dealing with financial disputes
- Ability to handle stressful situations with empathy and professionalism
- Excellent communication skills
