Well, according to their FAQ, they offer a trial service. So your friend would not have to continue to a larger report if the trial seemed to be indicating low benefits of further research.

Can I try MetaMed before committing to a large purchase? Yes. If your case has a larger budget, we can start with a smaller, trial report to ensure quality of service, and confirm that MetaMed is the right choice for you.

And they also offer Financial aid - There is almost no information about this posted, other than that it exists. I guess you would have to call to determine more about how it worked. If your friend did qualify, that would be a substantial boon:

Once you have consulted with our medical team, if you need financial aid to help with the cost of your MetaMed service, we will email you an application right away.

And it looks like overall there are at least three tiers of potential research:

Hopefully that information will help with deciding whether or not to contact them for more information.
