Boosting up my friend's site

Right now I'm very busy in my search optimising jobs, as I have to update my friend's site now so that I don't need to work tomorrow. He will pay me on Wednesday about $50 for 15 days full work with two absences needed to make up. He will pay me every 15 days worth $50 to my Paypal account for various search optimising jobs daily with hard effort. Even for extra jobs, it's only a little help from me but not good enough for his budget. Even for Peter, he will only pay him $15 per 15 days due to his little crappy budget, in order for him to save money and invest on campaigning his site.
