First time in Ghana - living costs and more

Hello,

I am in the lucky position to travel to Ghana next Wednesday for six weeks. I am going to conduct research for my final year project in St Patrick's Hospital in Offinso Maase. Hopefully in a later stage of my academic career I can move to Ghana for a longer period.

Now, I just wanted to gain a rough idea about the in country costs. I'll be living with a host family, which will provide food as well. Then I am in need of an interpreter, which a family member or staff of the hospital will be willing to do.

Here are my calculations for six weeks:

800 Cedi for accommodation/lodging
300 Cedi for interpreter
3350 Cedi to spend (which should cover any petrol/driver/shopping and other costs).

Are my calculations feasible or too much/little?
Thanks in advance for your answers.

Cheers,
Michelluu
