Ask HN: How to bring in a business partner?

Hi,

I have a very small forum of professionals of a specific field (let's say they are dentists), it has 3k daily visits.

I'm making big changes (moving to a better platform, better domain) and I would like to bring in a dentist onboard. The forum is not generating revenue but I think it has great potential (there are no big competitors in my country, and it's growing despite I'm making no effort to make it grow)

Without a dentist onboard, growth rate will be very slow. That's why I would like to have a partner or a employee to:

- Generate quality content

- Answer questions

- Invite dentists

- If the site growths: generate connections with businesses and find advertisers

I think that a partner will be more motivated than an employee, but I'm not comfortable by giving someone 50% of the (future) business without knowing how much will he work if currently there is no money, specially because the site is already running and growing.

What do you think is the best path to bring a partner?

1- Should I hire a dentist for some hours per week and later ask him if he wants to become a partner? I think this is the best path, but it's expensive and I do not have a lot of money.

2- Should I ask him if he is wants to volunteer until the site growths from 3,000 to 6,000 visits and then he will have 50%?

3- Or should I just him give 50% if he commits to work?

Thanks!
