Level about user

Hi,
we are developing a social network about sport with your beautiful software.

Now we have some doubt to do what follows:

a new user can register as "palyer" or "sport structure", and this is already possibile with 2 kind of profile.

if i register like player, i have a basic info page where i can put name surname email ecc and we wanna have a "addictional info" where i have to choose form a list every sports i practice (from a preimpostated list) and a "level of ability" for each sport.

This level should be :

- begineer
- medium
- pro


and thoose field should be selectable in a search option

example i want to search a registered beginner tennis player not so far as 50miles from me

how can do this ? every tips will be appreciated

Regards
