Write a pattent for a specialized piece of sporting equipment

I've got a device that I've manufactured and it's selling really well in my brick-and-mortar billiards supply store. I've decided that I want to branch out and sell it internationally through an online store. Of course, I want to protect my design which is unique to the industry. I need a pattent written for my device. It consists of 3 interlocking aluminum pieces. When assembled, it is about 4" squared. I have the original 3D design file for it and can provide physical samples for you to measure and document. I want a patent written by someone with prior patent writing experience, preferably in the sporting industry. I've investigated the patent writing process and I just don't have enough time to do it properly for my device. Strong English skills are a must for this project, so please consider that in your proposal.
