How can someone without a pilot's license arrange an initial test flight for a homebuilt aircraft? I think this has more to do with culture and expectations than actual rules, so maybe this might attract opinionated answers, but I still want to know what people think:

If a person were to construct their own homebuilt, like a Kitfox or RV, without first obtaining their PPL, how can they go about completing the 25 hour initial test phase required for the new aircraft?

This encompasses a subset of questions:


Is it customary to pay an experienced pilot to do it, acknowledging the risk involved with the activity? 
Or is free use of an aircraft and loggable time/experience compensation enough? 
Is it generally hard to find someone willing to do this for you (maybe do this with you is a better phrase since you will be part of the ground crew)?
Even licensed, experienced pilots often hire other pilots who have experience in test flying and hopefully time in the same model to perform the initial flights. Expect to pay for the service; test pilots do not do the work to build time. How hard it will be to find someone to do it depends on many factors such as the type of aircraft, the reputation of the design, your location and your willingness to allow the testing to take place at a safe field, the quality of your work, if you worked with an EAA chapter and at least one advisor, the quality of your build logs and photos, the quality of your flight test program docs, etc., etc. The EAA can further advise you on this, the membership fee is well worth it.
