Find a co-founder & work on a personal problem to solve (because you have no ideas) #6 & #7~ http://www.paulgraham.com/notnot.html
Find a technical co-founder that can program, work on a problem that you have (hint: maybe it could be I can't find a co-founder) #1, #6 & #7 ~ http://www.paulgraham.com/startupmistakes.html There is a problem with non-technical founders having the right location, some seed money & an idea. The idea will probably change so being obstinate is a mistake #5, #6 ~ http://www.paulgraham.com/startupmistakes.html The key thing is a technical co-founder(s), pronto & see if their skillset complements yours (btw you didn't mention what area you graduated?). Think Woz & Jobs for example.
You need to find your Woz!, your idea and move from there.
"... and the application designed in adobe illustrator ..."
But this is a sketch right? There are lots of problems thinking this will be your end product. It will change. The most important one being, "is it what people want (& willing to pay for)?". Obstinacy is a mistake #5 ~ http://www.paulgraham.com/startupmistakes.html
