I'm new in freelancer but i have 10 years of experience modeling texturing and rendering, you can checkout my portafolio, very good quality in matter of hours, also i'm an architect and i know how to sell an image by compositing and postproduction the final image, each image has the dedication that's needed to sell the project, you will have all the corrections you want till the final date or the final image is completely approved.
The best way to start de job is that you send me all the information, i start with the modeling in 3Ds Max 2015, then the texturing making real texturing with Photoshop, next rendering with Vray and finally postproduction with Photoshop, I will deliver the final images in JPG format, size tabloide RGB at 150 DPI, or if you have other requirements just let me know.
You can see some of my work in my portafolio
Sincerely
Marco Gasparin Budjevac
