Hi, Myself Pragya.
I have been working as professional Architect and Interior designer for last 5 years.
I am quite handy with Autocad, 3D modelling software like, Sketch up , Revit, Lumion, 3DS Max and Solidworks.
I provide all sorts of architectural services, 3D modeling services, 3D modeling of interior and exterior of residences, offices, commercial shops, mall etc by using SKetchup and realistic rendering using Vray and Lumion.
I have gone through your requirement. I am quite good with Sketchup modeling which you can see through my portfolio. I can help you in detailing out your existing Sketchup model of 2 story house with interior fixtures, furnishings and details. I use Sketchup 2017 and if you are using higher version, you can please save it in lower version and send to me.
Please refer to my portfolio for some of my work.
Warm Regards
