Hello. I really love money and I could bet $ 1,500 as you suggested. But I will be honest. This work is objectively cheaper. I’ll do this for $ 700, including commission payments from this site, but not including prototyping components. I have a lot of experience in this industry (20 years) and I have a well-equipped laboratory for this. Unfortunately, the site does not allow to make a bet of $ 700, but my proposal is valid. If we agree, then you heard my price. Regarding the deadlines - this may change for reasons beyond our control (the delivery time of the components and the production time of the printed circuit board for the prototype)
