I realize I'm brand new on this site, but I'm a professional designer currently working in-house for a sizable financial institution looking to pick up side work, so I have plenty of professional experience creating fillable PDFs and handling technical information, disclosures, etc. However, if this work is for a competing financial institution, I will obviously have to decline.
In order to give a more better estimate, I will require a lot more information from you, for example, how many pages you need, what fields need to be validated, will any kind of security be required, will you be requiring stock photography or copywriting, and what kind of branding you have set already, and where and how this fits in with other client facing materials, etc.
Feel free to message me with any questions or additional details you have.
Thanks for your time, and good luck with this project!
