Hello, How are you?
I'm Wayan
I'll jump straight to your brief;
1. I'm a pro architect with more than 15 years in practice and I've never knew or heard anything about Chief Architect software, but for sure I know a software known for their tag line as "3D FOR EVERY ONE" called SKETCHUP and 90% of my work in practice based on this program.
2. If you give me the chance to discuss a little bit in depth about the English Manor house you desired, I'll show you some examples of English manor style house design with SKETCHUP and you can see how the possibilities you will have with it and to explore its full potential in creating a customized house design.
3. You mentioned you need some one who has the experience in producing workable set of drawings, be patient in putting it all together, and almost no time bound - I think it is exactly why you are actually the right candidate for a high end professional freelancer. (only professional could put the design from conception to construction drawing and at the same time deals with any kind of client's set of character).
4. Design is always about creativity and ideas, and I believe this will be achieved with synergy between the client and the designer/architect.
5. Cost is a factor goes both ways for me too, so with the max amount of your budget, my offer is for the maximum of 5 days work on this project anything goes beyond it let's re-negotiate since normally I charge 200 USD/day. (please review the milestones I laid out)
regards
wayan
