The toughest thing is managing rent, bills and having a dream and goal. Really making the plans you have happen can mean putting into perspective the daily choices you make. Survival should be first, ( although for me sometimes it was last) it should be first. I know it might seem like life passes by fast and it does, even if you have to take a month off to get organized it is worth it....It might take some time to get good images, a comp card, and afford to put together a book, but after you do even 6 months of hard work and submitting to agents and to magazines could get you work and tearsheets. Within a year you could have some good work in your portfolio. Sometimes to get the bigger jobs and to get the agent you need a tear sheet to get you going. So if you don't have agency I would focus on trying to get tearsheets, and this can only take a few minutes of your day but you have to have your marketing tools. For printing try www.adorama.com/
But even with the modeling agent and modeling agency you have to always work for yourself, market yourself and be aware that nothing happens if you wait!
