What a cool service you offer!
Unfortunately, I don't need this service (as I suspect may be the crux of your issue). However, if I DID need a service like this, I would definitely not be "turned off" by your website. Sure, it's not the most modern-looking site on the web, but it does a nice job of communicating your service, showing fun examples, and describing how to contact you to get the process started. I can't imagine (no, I didn't research it) that you have a lot of competition; if that's the case, I think your website is fine.
Comparable example: I have a wool sweater that needs to be repaired. Moth holes. I did a web search, and there aren't a ton of businesses that offer re-weaving or wool sweater repair. The businesses that do offer this service don't have the most beautiful websites, but hey, that didn't stop me from wanting to use one of the businesses that's just one state away from me. The website was good enough to communicate the offer, show examples, and let me know next steps to get the job done. For something like that, I don't need an "Amazon quality" website. The service is more important than the website.
Others may differ.
