I'm looking for help designing my data structure

I’m sorry if this is “off topic” but I wasn’t sure where to post. I’m wondering if there’s any one out there who would be available for hire to help me design my data structure?

In a nutshell I’m trying to create an archive for my father’s architectural drawings (and other records). I can’t seem to find a vocabulary that fits my needs. I’m also confused on general ideals - how to track projects by client, etc. I do have relational database training so the general concepts are their for me, I think, I just need help fleshing out some of details.
