Hello,
My name is Jordan, I'm really interested in this project.
I'm a graphic designer and DTP professional with almost 20 years of experience in this area.
I also have great experience in PDF fillable form creation - from layouting and design to form calculations and scripting.
I have completed a variety of PDF fillable form projects using Adobe LiveCycle Designer and I could help you with creating your invoice template.
I have the knowledge and the skills to work on this project and will be really glad to.
Please check my feedback and portfolio (https://www.freelancer.com/u/sotisvw)
or contact me for more details, could provide you more samples on a private message.
Thanks in advance for your consideration, and I'm looking forward to hear from you.
Best Regards
Jordan
