What to Provide and Expect When Hiring Freelance HDMI/DLP Video Signal PCB Consultant?

Hi guys, so I’m not an electrical engineer myself and I need some freelance consulting help, happy to pay for the work, but need to know what exactly to provide to the freelancer, what to ask him to do and what information to expect from the consultation with low risk of poor provided information or even just false/ useless information.
I know where to get in touch with freelancers and have worked with them before having spent 3000 USD just this year but it always has been something I have some experience in myself such as CNC CAD mold design, optics simulation, programming or basic PCB design where I can check the submitted work and know what I’m looking at and if it’s good or not.
This time it’s a bit different, because it involves a very specialty video signal processing (HDMI, DLP) PCB requirements consultation to determine what minimum ICs or FPGAs are necessary to handle the job.
The information is available here as PDF:  https://drive.google.com/file/d/1vfFOLiVpvygosnE0BnyqnG9u2C69rhPF/view
The above info has been provided to me by Texas Instruments employees, however they themselves can’t recommend what IC or FPGA are needed for the project and they noted that their partners are only interested in 500,000 – 1,000,000+ pcs product design and development so they can’t help either.
if anyone could check and suggest what category of electrical engineer I should be looking for, what to ask to provide and  how to verify the provided consultation info is good it would be very much appreciated.

Hi Fred,From the job description in the PDF, it looks like you don't actually need someone to design the board but rather to select the correct chip or chips.If you want someone really good, you should ask them what they need from you and what they intend to supply to you. A good consultant is supposed to make your job easier and you're not expected to know the actual milestones, so they should actually provide the information to you.However, that doesn't always work in practice. Many consultants are good engineers but not good business people. So if your potential consultants can't give you a list of what they need and what they will supply, here is a list (off the top of my head) of what you should request from them:1. A schedule to get you the final recommendation for the chip or chips.2. An estimated cost.3. A list of what further information they need from you (you shouldn't be expected to know what they need).4. Their resume and a write-up of their experience in this area.5. References from at least 3 previous clients that you can call to ask questions.4. The deliverable at the end of the contract should be a written recommendation comparing several options according to cost, features, etc.
