Is this a good deal for first brokerage?

I recently got licensed in my state to be a real estate salesperson and got a job offer. Its a 13k per year desk fee that is paid with a 50/50 split till it is paid. Once I make 26k total in commision I get 100% of my commisions. This includes a desk, advertising, business cards, internet access and leads and voicemail and a web site. It also lets me sell my own properties for a $250 fee and buy for a $750 fee which would be good because the main reason I got into this line of work was for flipping houses. Does this sound like a good deal?
