Pages / Forms / Datafields

My install version is 12.1.0 (I'll upgrade to current when I'm finished configuring my site, long story) I've installed Posts, Developer and Persons apps. The site is not intended to be a "normal" community.

I'm going to be running an TV AD campaign with a call to action to sign up on my new website for Sports Videography.

I need a landing page where visitors can input their contact information and location info (address), select from a pick list what type of video they want produced, hard date for when they need it completed by, and possible dates for filming, and if they have any existing game footage. (I'll need a page where they can upload the footage at a later date, and the upload should not convert the video. It needs to stay in it's native format. The video uploaded will not be for display / sharing, but for me to download and edit.)

I've figured out how to create a pick list in the Navigation app.

I've figured out how to create and publish custom pages.

Is this something I can do in the Developer App or do I need to go to the Database and create a new table, then write the code to access that table for insert / update / delete actions?
