I like Red Prince's answer here...
It's like asking someone for advice on becoming a top-notch chef and asking "What stove should I buy?"
The largest hurdle to becoming a top-notch chef is understanding cooking at an unusual depth...not buying appliances.
'Top-notch' equipment and 'budget' are tough to apply to much in this business. I don't know what "Hollywood-status" is in post production other than having a staff that has "Hollywood" experience, but I do know that the color correction/DI software that I like, Iridas SpeedGrade DI, costs around $50,000 USD...and yes, I said software...the computer is extra. This software is an amazing bargain when compared to buying a Lustre workstation or a Da Vinci system, which run many times that amount.
Regardless of the tools you use, having the skills is what will bring in the high-end work.
Maybe not what you were looking for...but I think that these types of references to "Hollywood" are tossed around a little loosely these days.
There are many independent films that are post produced in facilities that are far from anything that a main line A-budget feature film would even consider using. Post production facilities of a wide range exist and create income for their owners. It's a matter of matching your skills to the right projects...and then get whatever equipment those conditions dictate.
