Finding a partnership

I am really interested in finding a partnership to buy into.
interested in a time building plane that can also be used for flying
with friends and family (ie can't be a 150/152) Any advice on the
following:

1. how does one go about locating an existing partnership

2. in the absence of existing partnerships, how does one recruit
others to go in on a plane

3. any advice on buying the plane outright and selling part interest
in it to others

any and all discussion is much appreciated.

regards,
gf
