I am not sure
To be honest, i am not sure if i would be able to figure these out or not, but i dont see it as a problem or something that i wouldnt be able to do.
I maintain my own bookkepping for all expenses and payable on a excel sheet. I keep a record of what i purchase on my credit card, and always on time with the due date on the payment. I am very detail orientated when it comes to finding out how much i need to pay and how much i would receive monthly as in terms of my own paycheck.
I never had a chance to do any kind of intern, so if everything base on resume, i wouldnt have any experience. But i am a quick learner. I dont think is hard. I truly think i can do a good job.
Since you mention the temp job, how does it work exactly, can you describe it a little bit more? I am willing to do extra work on the temp job, but i cannot drop my current job because i need the income to take care of my family.
