Hunter M.
Before law school I built the contract management system for a publicly traded medical device company — so I read your agreement the way the people who have to live with it will, not just the way a court would. I draft and review business contracts on a fixed fee, with the delivery date agreed before I start. You get the redlined document plus a short written summary of what I changed, why it matters, and what I'd push back on if the other side objects. Revisions are included — I'd rather get the document right than count rounds. NDAs, MSAs and SOWs, contractor and employment agreements, SaaS terms, terms of service and privacy policies, operating agreements, vendor and construction contracts, and full contract review with a plain-English risk summary. Send me the document and what you're trying to accomplish with it, and I'll come back with a fixed fee and a date.
