General - Photo editing advice

I'm trying to make a poster collage to send to a print shop and have it pasted on a wall... The print would be huge (around 100 inches tall to 150 inches wide), and so I wanted to put various poster images in one sole image to send it directly to the print shop..
Yet the problem I'm having is that when I try to create such a big image canvas, the image editor (Gimp) is telling me that such a size will consume 4.8GB of memory, that if I'm sure I want to proceed...
So I cancel and create a poster size image (around 100MB!!) and start adding large poster images and expanding the canvas size, and ideed the Gimp process starts consuming lots and lots of memory...
What I don't get is... If i'm adding 3MB to 10MB jpeg image files to the canvas, why is the size so huge? I know that jpeg is compressed, and that the image I'm working with is uncompressed and probably that's the thing... But the main question then is: how can I do this without breaking my pc? How can I create a collage of compressed JPEGs and obtain a simple (say) 30MB jpeg file??

To really control it I'd advise using photoshop - you need to be sure that 'all things are equal' in terms of resolution, sampling etc.
A very large, high-res image will be very large.

photoshop and gimp are not meant to do this. while editing a jpg in one of these programs, it gets decompressed, which consumes gigabytes of memory.
A possible solution would be the use of a program like Adobe InDesign

buy a new pc ! a better one.
I'm graphist and we use photoshop to make artworks which will be print on vinyl banners ( sometimes up to 10 meters) and usually our artworks are never up to 250 MB, we send the artwork file in pdf.

Graphic designer here also - Generally in my experience of large scale print - eg billboard it is of course scaled, but you do need it to be of high quality in the first place - InDesign is a layout tool, but it does not edit graphics in any way so you will not be able to ensure all images are same size/quality - it will allow you to construct your poster however.
Photoshop is your best bet - then talk to the printer and find out what type of printing they support - what resolution they advise for scaling and also ask them for a colour profile so you can wysiwyg the whole thing
