Each of my engagements starts with a Master Services Agreement. This is my standard contract for all clients, and it covers legal basics like IP and payment terms.
You can sign this with your preferred digital signing service (Docusign etc), or just add your signature with Preview (on Mac) and email it to firstname.lastname@example.org.
I'll also send you a customized Statement of Work that includes details about our project.
I've tried to make this process as quick and painless as possible. If you have any questions, please email me!
