Payments preferred through the Guru Safepay Escrow system. You control the funds but also guarantee them for payment upon acceptable work deliverables. A Project Plan is used for both parties to agree on deliverables, dates, and scope of work.
For subjectively large and/or lengthy projects a token "get started" payment is required, typically 20-25% of the estimate. If the project has clearly defined stages then I may require milestone payments as the project proceeds.
In any case we can reach a workable agreement. We both have common goals.
