I have an embroidery machine and I enjoy using it a ton. However for your project no way! It would be too expensive, the learning curve too steep and the frustration level off the charts. To use one of these machine takes lots of practice, many trial and errors and lots of expense. For a project this size I'd do hand embroidery and/or writing with fabric pens or paints. Ask friends with embroidery machines to see if they would like to take on the challenge in trade or for payment.
