Hi
You don't say anything about the pcb complexibility is. However I'm bidding as I know very very well Design Spark (working for more than 20 years with its genuine program EASY_PC from which the Design Spark was made as a "brother" program under contract for RS).
The bid is valid only if your requirements are for a pcb of maximum 2 layers, and not more than 100 components SMT or THU (excluding the use of BGA IC packages)!
Delivery of full Gerber/NCdril and BOM for production!
UPDATED: Since you asked for examples of work with Design Spark, I have to update my bid accordingly. FYI Examples of finished pcb designed with it are available at my portfolio! You can have a look at them. To send you files is not possible as most of them are with NDA and I can't provide it freely (like the one you want me also to sign for getting the job and I'm sure you wouldn't like to share your project to others in the future, as an example of work) . Also bid is increased somewhat, as I consider that running parallel project is a kind of back-up method, since you have created a second exactly same project - Project ID: 12674613 https://www.freelancer.com/projects/Engineering/Must-Good-Using-DesignSpark-for/ - that you have already awarded to someone before 3 days, you should have your task done by now since he should have delivered next day from assignment.
