How thoroughly have you compared yourselves to existing options like Invitae? They appear to offer pretty much what you are describing for a similar (slightly higher) price [1].

I feel like you may be underestimating both the maturity of the existing market and the complexity of doing what you are proposing at scale. Are you issuing clinical reports for your results? If so, who is doing that as neither of you sounds like you would meet the normal requirements for that.
