By just taking on wireframes/samples you'll need to find multiple customers consecutively (eg they need to be one each week, as two simultaneously would be too much work on 2h/day)
Why not instead offer to port an already successful iphone app to android? You have over 2 months and only need to find one client...
I know we have a couple of smaller projects we'd definitely pay 2k + for if done properly.
$2k in 3 months, at 2 hours a day. Lets say you need 50% of that time to hustle up clients, so you have 254=40 hours a month, or 120 hours total (and you don't even have to work weekends). 60 billable hours, so you'll need to charge 2000/60= $33 an hour to make your goal which is far below what any professional developer should be charging (assuming you're in the US).
One good client should be enough. The hard part will be finding that client. Go to your local meetups, user groups, cold email intros to local agencies (agencies are great for overflow work), local startups who have an iPhone app but not an Android app, etc. Have coffee, pick up a few lunch tabs, establish good relationships. Relentlessly follow up and ask for projects. Don't underprice. Whatever you think is reasonable, double it and practice saying it with a straight face in the mirror.
If you are in such desperate need, commit now and start today. Otherwise try to find a freelance position or something with more structure.
Maybe get a second job? Does your company offer overtime pay?
1. Build a list of potential customers. Ideally names and phone numbers.
2. Write a script of what you will say on the phone.
3. Call them all with the aim of booking a half hour appointment (in person or Skype if too far away).
4. In the appointment find out more about their problem and pain points, see if you are a good fit to help, try to close the deal. Require upfront payment.
5. If in 20 hours of cold calling you can't get anyone to hand you cash then pivot.
...Or beg or borrow :-). Or maybe get that second job and resign after 3 months.
