Just my two cents,

Get a hot shot,, just a D battery with a end on it, it comes with a charger. That should be the biggest expense at first.

I'm not counting fuel. If you have a way to start your plane, at least you can test the engine and run it up at home if you want to.
A starter is expensive and I would wait to get one until you go to the field a few times, get a hardwood dowel and make a "chicken stuck" just put some tape on one end so you don't damage the prop. If you have a good motor you might be able to start it with a chicken stick. Some of the motors will start right up and some won't.
you can buy a squeeze bottle cheap or make one and use it to fuel your plane, they are a big hassle and anyone who has one will most likely give it to you.
I had a hand pump but wanted a electric one, it took me over 3 years to give it away... to someone who needed it.

Keep in mind that the most helpful are not always the most knowledgeable, so keep you eyes open.

In an earlier post I was exploring the question: who would be best to help, even though you will have to seek out his time and he might not be the first to rush in to help.

I think your yardstick should be landings... It has been my experience that the guys who do the best landings are the ones who really know there stuff.
I don't have any thing but my own experience to call upon, but as I look back, it has been the ones that everybody stops just for a second to watch land that have been the shining stars.

Good luck Impulse,
