Then you only need reputation/trust. It might work to not invest any money and stay around here, help out, express your opinion, etc. ... but I think you need to get seriously into mining first (at least 6 to 12 months), before you can suggest joint ventures (and expect someone to move his/her mining infrastructure to your place).
