Hi
I can certainly provide you with the output you need in a good time frame. I went ahead and produced one of my own which took approximately 7 minutes, which equates to around 23 hours of work for all 200. This means a rough price of $10 per plan for this job.
Freelancers biding at $250 are actually working for $10 per hour. A Freelancer who works for that, can not have purchased a legitimate copy of AutoCAD or be a Professional, that then means, are they going to be reliable. I have over 20 years of experience with AutoCAD and this job is not too difficult but just time consuming. I was a little uncertain if the expected price is for one plan or all, and I am just wondering if it might be an idea to mention that in the project description.
Regards Neil
