Wordpress contact form won't accept a Javascript link. Code the link to be compatible with wordpress for me!

I have a [login to view URL] website and as it turns out, it does not work with Javascript. I just recently swapped to a studio management software called honeybook, which provides a contact form that will link from my website directly back into the studio management software with the information my clients input. I need this to happen because it will automatically trigger emails and a whole plethora of tasks that need to be completed upon receiving an inquiry. Unfortunately, honeybook only provides a javascript link that won't work! I need to know- is there a way to somehow change this javascript into something that will work the same way and input the info from my contact form on my wordpress into my studio management software? If so, I need to know three things! 1) How much will it cost? 2) How long will it take you? 3) What is your favorite ice cream? Thank you! Ashley
