It makes a huge difference. Graduate programs in counseling require supervised clinical hours, and it would be difficult to complete those at a distance.
You don’t need to major in social work to do an MSW, but if you do get a BSW you can usually get your MSW faster through an accelerated program.
Do you really, really want to be a counselor or are you just looking for a nice lucrative fallback for your photography career? I wouldn’t discourage anyone from becoming a counselor or social worker, because we need those and they’re good professions. That said, they’re not necessarily good “fallback” careers for someone who is starting from scratch, can’t afford a lot and is really pursuing another career as a primary one. Even if you plowed through full-time it’ll be 6 years between now and when you can be a licensed counselor, and if (more realistically) you attend part-time while getting your photography business off the ground, it’ll be close to 12 years or more.
Besides, it’ll be difficult to find any online program that you can cover with just the money from Pell plus state grants, if you are eligible for any. And an online program will make it difficult to get into a PhD program in clinical psychology down the line, because there are certain things you need (like research and clinical volunteering experience) that are difficult to do at a distance from a university.
Either way, if I were you I would stick to brick-and-mortar, non-profit, accredited universities that have an online component to them. In other words, no Capella, Walden, or University of Phoenix. They’re going to be more cost-effective anyway, but they will also look better on your resume and your application to graduate school.
With that said - Southern New Hampshire University (SNHU) is also pretty inexpensive; they cost $320 a credit hour or $3,840 per semester if you take 12 hours. That’s still more than Pell will cover, but not a whole lot more - you might be able to cover the shortfall with state grants or money out of pocket. If you attend half-time at 6 hours, that’s only $1,920 per semester, which you can more than cover with Pell - but it’ll take you longer than 12 semesters to finish.
Oregon State online is also very inexpensive - they cost $280/credit, so $3,360 per semester if you take 12 credits.
Liberty University online costs $375/credit, and they have a specialization in Christian counseling too.
Penn State has an online BA in psychology, but it costs $6,506 per semester if you take 12 credits a semester (and $535 per credit if you take below that; that’s about $3,210 if you are taking 6 credits in a semester). That’s honestly pretty cheap for an OOS public university, but still more than Pell will cover if you refuse to borrow any money - although if you borrowed a small Direct loan you could probably cover it. http://www.worldcampus.psu.edu/degrees-and-certificates/psychology-bachelors/costs
Arizona State online is $500/credit, so $3,000 for half-time and $6,000 for full time.
Drexel online has a special for 2016-2017 where they’ve reduced tuition to $479/credit, but I don’t know if that means your tuition will go up in 2017-2018 and beyond.
