This is a business arrangement between employee (houseboy) and employer. Much like the hiring process in a typical business.
The employer has a job opening.
The houseboy posts a resume (profile).
The employer looks for a resume that matches his requirements.
The employer initiates contact expressing interest.
The houseboy checks the employer's profile and decides whether to return contact.
There is some back and forth communication.
If the initial cut passes there will likely be a job interview.
Which, if successful, will lead to a job offer.
It seems that a critical factor in receiving a successful job offer is having a good resume (profile) posted. So, if you are a legitimate houseboy I would suggest:
Act like you're applying for a job. Your "resume" (profile) is what will make the initial cut with prospective employers. So keep it up to date. It is amazing how many profiles here have not been updated (edited) in over a year - and you're serious about seeking a house boy position?! REALLY!
