Build a Website

I need a simple database website for purchasing items like pump, compressor.. Attached is an example of one item "pump". I want to be able to add to more items later on myself. There could be 500-1000 items. The first menu bar should be a searchable dropdown bar/menu. So, when the user select (or type) their items, a questionnaire menu will pop up (attached picture 2) and they have to fill it out and submit it. Upon submission, an email with the user input data in table format will be emailed to me and a confirmation will be sent to the user as well, also a "Thank you message and my phone number will appear for immediate assistance". The user don't have to fill out all the options in this form (just some that are necessary with * next to it for instance). At the end of this form, there will be a puzzle or a question to make sure the user is human. There are a few ways to make this puzzle. I saw one in one of the websites which I think it is really cool (See Picture 8). It doesn't have to be like this though, if it will be very complicated to code. Some websites chock when you refresh the questionnaire page or refresh the puzzle. Each items (Pump, Compressor, valve..) will require different parameters in this form. As I mentioned, I just need someone to do the first one or two items and give me a clear instructions on how to add more items. I was thinking to use Python Django, since I know a bit myself. A simple "About" page is also needed.
