Hey there! :)
TribalWars scripts seem to be fairly straightforward thanks to the game being JavaScript based. That said though, I'm curious just how complicated of a script you'd be looking for. After all, there's quite a range of possibilities, and your job description is admittedly a bit open-ended, and it's difficult for me to give a fair estimate on budget and timeline without knowing the specifics ahead of time. That said though, I'd be interested in talking with you to discuss what you're interested in.
As for the standard "about me" formalities, I've been using JavaScript both professionally and as a hobby most of my life, and I've been freelancing as an expert in JavaScript for quite some time now. By all means, feel free to check my profile for a few testimonials from past clients, as well as to get to know a bit more about me.
With that out of the way, I'd love to hear from you as soon as possible. Toss me a reply so we can get started right away! I look forward to working with you. :)
