Active job

Put in new toilet into 7 year old house by Monday next week

My house is 7 years old, has a large bathroom with no toilet in it, but plenty of space. i would like a toilet with a P trap put in, against the wall which backs into the garage, with waste going about 2m along internal garage wall (we can fit into wall, want to leave linings tidy in bathroom and do any access from garage side) then it can be taken out thru wall and bricks into trap that sits just outside bathroom. I considered cutting a chase in floor for waste but the bath is right along the outside wall of the bathroom so would mean pulling this all out etc. Water supply is up in the roof now so that shouldn't be too hard, again can access wall cavity from garage side. Is anyone keen, i need a price for the whole job, fittings etc, i will just supply the toilet itself. I don't want to have to get a permit as don't want extra cost, but everything must be done up to proper standard. We have guests coming next week, hence the rush. However i would need an approx quote first, then a visit and firm quote prior to any work starting. As i said, about 2 m of internal sewer pipe which will run along internal garage wall, then take out thru the garage wall and join into existing gully trap which is just outside the bathroom. Floors in bathroom are just lino, and wall linings are gib.
