I need to get my house transferred from photographs to a Sketchup model

Design details: I'm planning a new addition to my house and I need a sketchup model that I can use for visualizations of different additions. I have a set of photographs in which I have added a number of measurements to make it easier to make a computer model. Another help might be that the timber claddning is 11cm wide. All the measurements are approximations. It is acceptable if details are not fully to scale and some minor things are left out. The important thing is to get the overall sizes, placement and proportions right.

All measurements have not be repeated on all pictures since they are the same on all sides. It is recommended to start with the side facing east(most measurements).

The side facing south has a small entry way in the picture that is not needed in the model as this is the part that will be replaced.

If additional measurements are needed please let me know.

I would like to get two quotes:

1) A non-textured version (something like this https://lib.store.yahoo.net/lib/vintagewoodworks/ei-opg-shedroof-1)
2) Additional cost for a textured "real life looking" model as on option (something like this but with out the garden additions etc, http://myfavoriteheadache.com/img/65507/8a4cbfa0cf72432b40d9c6ace2729c8c.jpg )
Ideas for the visual style: Please see attached photos
Extra notes: NB. I was only allowed to upload three photographs. Please contact me for the last one i.e the south side of the house.

Any currency will do, USD, EUR or GBP.
