<human>: I've been lurking here for a while and reading all sorts of great pieces of advise, but I have a question I can't seem to find a solid answer to and would like so advise.

I have a lot of hobbies and would like to try and start possibly making some money off some.  In order to do that my expenses would have to come out of my personal checking account.  I do not have a local bank (I travel for work alot, often a year or more at a time).  What are the pros/cons of some different payment methods to pay myself back? Square personal card reader (I would assume the most convenient for all parties involved), I can scan a check to my bank to make deposits (but I forsee check usage as the least common form of payment), cash (I would open a local bank to transfer money back to my original bank account), or PayPal (not my favorite option, mostly because I have only used it once before and don't really understand how it works).  Pros/cons? Other options?

Lastly, I don't forsee myself making alot of money from this, just enough to make some playing money since I'm already on kind of a tight budget.  How would something like this affect me come tax season?  Is there an income threshold that I should be conscious of?   My expenses  could range from $300 to $1500 and I would most likely profit 25% of that (roughly $75-$375 give or take)

Give me the gist of the text in a nutshell
