How much would this kitchen cost (or how long is a piece of string)?

[AllBoxedUp]

Hello. I really want a new kitchen and am considering getting a 5 year loan to pay for it. I was thinking of borrowing about £10K over 5 years but I don't know if this would be enough. The kitchen is about 3m x 3m and there are units on 3 walls (although one wall has an exterior door on it). I think we would keep our existing washing machine, dishwasher and fridge freezer but get an integrated oven/hob. I think we could also keep the existing flooring.

The existing kitchen is a pretty ropey DIY job by the previous owner. One unit in particular has no back and is onto bare brick wall. We are getting field mice coming in here and I am hoping that getting the walls sorted would sort this out. Our fuse box is also at the back of a corner cupboard and looks a bit dodgy.

So we would need:

-kitchen removed
-wall tiles removed
-walls replastered
-electrics sorted
-new units fitted
-ceiling sorted (it's DIY tongue and groove at the moment)

Anything else? Does this sound realistic? Would I be better using a builder who could do everything and maybe fit a Howden's kitchen (if I could afford this) than get a Homebase style kitchen (could they do the other stuff)? Thanks for any replies - I did get lots of ideas about trying to do as much work as possible ourselves before but I'm feeling a bit more daunted by this now as we didn't manage to do anything before our DD arrived in May.

OP
My kitchen is on my profile pictures.
The units are Ikea and cost £3000 a few years back.
The appliances cost under £2000
Fitting cost £800 to a chippy

it went into a new build room BUT a decent jobbing builder could gut the existing room in a day or two - so for £500 tops

Thank you - that's encouraging. I do like Ikea kitchens but I guess I would have to see if the guy I have in mind would be ok fitting them. DH thinks he might be expensive but he's someone we've used before and I know he would do a good job.
I should have mentioned that we got a phone quote before about the electrics when we were buying the place and the electrician thought it sounded like something that would be about £1K max to sort based on the survey description. I also think we could keep all the plumbing as it is.

Nice kitchen too - I really like the tiles.

Tiles came from our local independent supplier : end of line, cheap. DH put them up.

I redone our kitchen a few weeks ago (we are currently refurbing the whole house) 2m x 3m, units were £998 from IKEA. Only downside was the service gap behind the cabinets isnt that big, other than that im really impressed with them.

We ripped out old kitchen ourselves and removed old tiles ourselves which was simple (and good stress relief)

You may want to get an electrician in to quote as I found that they were not happy to just rewire the kitchen as my wiring and circuits for the house were out dated. We also found our plumbing need redoing even though initially we thought it would be OK.
