So I'm doing some ghetto carbon layup and I need a way to get a vacuum going on the bag that holds all the resin and parts in the mold. (Creates an optimal carbon to resin ratio and reduces waste)
With that being said.. I'm not looking to drop a few hundred on a dedicated vacuum puller like picture related. I've seen a few other methods, like a venturi system hooked up to an air compressor, but I'd also have to buy an air compressor from harbor freight or the likes. (Which means, more money spent)
So any suggestions?

I have a simple vacuum pump intended for HVAC applications. Was like $60 off eBay. Works great for resin/silicone casting.

Appears to be essentially identical to mine.

Guess I'll bite the bullet then.

Show us some of your work dude.
I've done loads of fibreglass in but never used a vacuum system

Get down to the local Goodwill and pick one up for a few bucks.
A vacuum cleaner has the advantage over one of these pumps in that it can handle a few small air leaks and still pull a decent vacuum.

what is the reason that you don't want to use a vacuum cleaner?

Have you considered a water aspirator? It won't pull high vacuum but it's relatively cheap and easy.

You need a fairly high vacuum to do this stuff. It's best to go with the tried and true setups.

Try buying one of these in EU...they're almost 2x as much...

I'd suggest a salvaged compressor from an old AC unit or refrigerator will pull more than enough vacuum for your purposes. If you aspirate resin and lock it up... no worries they're cheap
