Hello
I have over 28 years extensive experience with Filemaker Pro and have developed, deployed and maintained many instances from very large and complex down through to small more simple deployments.
I have also worked with a number of web direct based solutions, including the security aspects involved to secure a front facing public entry point, which may help in this situation.
If you would like to send through some additional information on your project, including which version of Filemaker you are currently running, what kind and size of files you are expecting to be uploaded (WebDirect has a max filesize limitation which may come into play) and any other relevant details, we can confirm a plan and I can provide a more accurate proposal, with the some milestones that we can work through together to complete the project.
Thank you
Darren
