EchoSign API Integration FPDF/TCPDF & FPDI php app

Hello, We are looking for a Competent and Reliable PHP Developer who is familiar with, or can easily and quickly learn; FPDF/TCPDF/FPDI and the Adobe EchoSign API. Experience with Joomla is not necessary but would be helpful as we are currently developing a website for a client using Joomla! 2.5.8 as our CMS. We require variables that have been entered into a database through a form to be placed into a dynamically generated pdf. We have found that FPDF/TCPDF to be able to handle the pdf generation. We then require that generated pdf document to be digitally signed with an e-signature and a digital time stamp. We want the digital signing process to be handled by Adobe's Echosign API. Once the pdf document has been signed, we then want the document to be saved to our web server and have a notification sent to our client that the contract is ready to be executed (via email). This client will proceed to log on to our website via the front end and access that pdf document from the web server and digitally sign it himself. Once the document has been signed by both parties, a copy of the contract will be sent to all parties (via email) and saved again on the web server. We would ideally like this process to be accessible via the front end of our website. If the project is successful, we would be interested in hiring the developer on a regular basis as we have 3+ of these similar types of projects each year. We look forward to working with you. Thank your for your time.
