Whats the best way..., to support my car for rust work Options

[obscurity]

I am preparing to dig into my rusty 914 for sevaral jobs and I was hoping to get some input on the best way to support the car for work (economically). I would love to bUy a lift of some sort but I am afraid that they are all out of the realm of possibility (I've even checked on e-bay). Even the scissors style are more than $1,000

I will probably need to work in these areas:
-Hell Hole (and probably a little of everything associated with it)
-Long replacement (hopefully not but best to be prepared)
floors (just the back portion)
-some portions at the bottom of the fire wall
-There is some rust in the tunnel so we'll have to see what that is all about

I guess what I am looking for is a good all round method of holding the car in a good working position. I have looked at buying of fabricating a cart like this Eastwood Body Cart
but that may not give me the kind of access I will need. Any comments or advice is appreciated as I have never done something like this before

Thanks
