typically, an organizer will help you organize with what you have.
my friend is really good at consolidating. it's not really about new furniture or products, and she also is good at finding bargains for when that is a necessity. but part of her process is trying not to bring new things in, but really let go of most things that you don't need.
so, here is her basic process, as far as i understand it.
first, she goes in and gives an analysis of what she is seeing in the space. this involves, btw, a lot of talking. she asks a lot of questions about how you use the space, what your thoughts are on what you have, how you feel about your home, how you want it to feel, and so on.
then, she spends some time in the space without you. at this point, she's really looking at what you have and how you are using it. As an example, she just did a home where the client said she just didn't have enough storage to be organized. well, what my friend discovered is that she had a lot of storage, but she wasn't utilizing it well. So, she made a list of what the person already had, so that those things can be utilized most effectively.
the next step is actually decluttering. when you have figured out what you want to keep, she then goes through what storage you have to organize it. and then organizes it that way.
when there isn't a clear way to organize those things, she actually gets very thrifty. as an example, she helped a woman organize her pantry. admittedly--like our pantry--the space is large, but it's difficult to use because things get pushed to the back, tossed around, etc. so, it gets disorganized quickly. most people might assert that you should run out and get these kinds of organization boxes or those sorts of drawer things (like at ikea, which are great if you can afford them).
but my friend's idea was even more simple: old shoe boxes. she had some old fabric and grabbed those old shoe boxes and wrapped them up. each one was then labelled, and then spices in one, dry goods, etc, so that they were easy to pull out and use. Sure, not as durable as others, but functional and easy to replace if one breaks down. and, best of all--free!
sometimes, it's just about looking at your storage in new ways, too. for example, i used to have a dresser for DH, one for me, and one for the baby. now we are all in one--because i put the clothes we use in there, and streamlined our wardrobe down. then, i had a lot of extra drawers around. i could put other things in them (now, i don't even own them, because we let them go for our move to NZ). One held linens (cleaning out the linen closet). another held my husband's paper piles (it became a pretty fancy filing cabinet! LOL). and another cabinet for china became a bookshelf for important books that we kept behind a locked little glass door (so DS couldn't rip them apart!).
so, i wouldn't be too discouraged. an organizer will not necessarily try to get you to buy 30 containers form the container store. instead, she might just use boxes from the bottle shop, wrapped in nice cloth or some such.
