I need a backpack made

I have a New Look black backpack that I love but it's dead and I want it replicating in suede. It has the main bit, an outside pocket, inside pocket (I will probably want to add another inside pocket). It has padded shoulder straps (I would like to add a zipped pocket in the front of the shoulder strap for quick access to oyster/cards. The main pocket is double zipped and it has a hanging loop at the top. I would like all zips/metal to be gold in colour.
I don't know how much this would cost but I am looking for a quote. Maybe I'm out of my depth getting this handmade but I can't find a bag I like and figured may as well get one that will last?
On a seperate job I am also looking for a tailored black/brown leather tobacco pouch that has a lining to keep my tobacco from drying out - also have a cheap one that is falling apart to be replicated - (as per the photo with a zip on the back for filters)
