Cost estimate to build web application

I've been building out a database and getting ready to hire a web dev (hopefully this doesn't turn into spamming my inbox for a job, lol). I was wondering if i could get an idea of what a quality north American developer would cost for this project.

Here's what I've got

* Single sheet database loaded onto dynamoDB (no relational database, just one sheet) * S3 photobucket with photos that correspond to the dynamoDB

I'd like to have someone implement a simple web app that would utilize this function

* Users provide inputs for a multi parameter query (Vehicle Make, Vehicle model, vehicle year, etc, etc, etc) * User can see how many queries are a match and price will be based on the number of queries, price displayed as queries are changed * programmatically generated powerpoint based on the matched queries using [https://python-pptx.readthedocs.io/en/latest/](https://python-pptx.readthedocs.io/en/latest/) This would involve placing 2 photos and some text info into the powerpoint for each query * User can now download the powerpoint

This is in a microniche, so total users should be well under 10,000 worldwide, probably not much need for scaling implementations.

Hopefully this isn't an inappropriate post for this subreddit.
