You can not determine a quality to get a specific filesize, except by trying it. The best way is to say try 75% and see the result if to large reduce by 10%, if two small increase. Then do a binary search to find the quality that best matches what file size you want. Shouldn't take more than 5 to 6 trys to figure it out.
