Hello Andezign,
I am Architect Ms. Jigisha, a team member at JJdatajobs (with my husband - Jitendra). I have practiced architecture for 15 years. Now I am 'At-home' worker. I do not know if you want to consider an Architect for this project.
I would like to take this up, because it appears from the project brief that you shall be having such drafting tasks on a regular basis. I am quoting fees as an example. Actually, you could be having designs in different sizes, with different details and therefore, the fee calculation shall not hold good for other designs.
If I may suggest, we could work on hourly basis. My fees shall be $20 per hour. This kind of design can take about 2 - 2.5 hours, for presentation drawings. If you think this is a workable proposition, I shall be happy to draw this as sample. You could then decide whether you would like to continue with me.
Your reply shall be awaited.
With regards,
Ar. Jigisha.
