A four stroke kit would work. If it doesn't rain much where you live, installing a friction drive kit is the easiest.
Budget is indeed a factor.
Your Sealed Lead Acid (SLA) batteries are the thing cars use for a big boost to start it.
Lithium Ion batteries pack about the same punch at half the weight and size.
Heck ya they cost more, but not twice as much and why you don't see SLA's in cell phones, laptops, or electric cars.
