I'm going to quote some of the material from GBFans, which details some of the costs and details involved.
Finished Proton Packs with lights and sound often sell for around $3,000. Minus the sound, that comes down to between $2,000 and $1,500.
These are the sorts of figures you should keep in mind as the high-end of the scale in terms of value.
There's another excellent post which I'll quote, which lists the various parts that are available:

Goodluck with that, It is rare to see a complete Proton Pack with lights and sound ‘For Sale’ It will happen, and when it does be ready to pay anything up to 2000 bucks.

The proton pack is very much a registered trade mark design and while we are okay selling parts to build one, selling a complete proton pack on a regular basis I believe to be very illegal.
Then again, there is also all the following links that would send you on your way to owning an awesome pack.

The Three major players in the Plans are Stefan's, Seans, and Norms.
Stefan are straight out BluePrints. No explaining, Just the figures.
Norm and Sean have excellent walkthough like instructions. Great for new GBfans.

It may seem like a daunting task, but I believe that anyone could put together a passable proton pack if they just devoted themselves to it. I made my first attempt at a proton pack at the age of 12, and I got a lot of help from some handly adults in my life. It turned out pretty good. If any of you Jokers have my old “pack reference” VHS tape, there is a segment at the end of me cavorting around in my first pack.
Either way, the point here is you gotta learn to LOVE the proton pack. Even if it turns out looking like a total piece of shit, its still a product of your own design, and no matter what any f**** says, it's an achievement. Not too many people go out of their way to piece together a prop from some “dumb movie from the 80's.”
Anyway. This is a project that requires a small bit of devotion, and you need to realize that before you wish to obtain a good proton pack (a good proton pack by the standards of myself, and all the sticklers here)
If anyone has any more ideas or resources, slip me a pm and Ill update the list.
I hope that isn't too daunting.
The thing to remember, is that on here and GBFans there are people who can provide help.
As for where to start, I suggest perusing the Proton Pack plans on GBFans:
Equipment Plans-to see which one you feel best suits your level of comfort and skill.
Norm's plans are more relaxed, but should be taken more as a guide then a definitive set.
Sean's are much more detailed and go through a sort of step-by-step process.
Stefan's are the most detailed, but do contain some mistakes and are measurements only.
I recommend building a Pack if you can, even though I didn't build all of my Pack myself, there's nothing quite like the feeling of owning a Pack you've assembled with your own hands.
I hope this info helps.
