If you want to make stronger beer, you need to pitch multiple packets of dry yeast, 2 or 3. Or better yet make a starter with liquid yeast thats of adequate size. Google "Mr Malty", and open up the yeast calculator. It'll give you an idea of how much yeast to pitch based on what you're brewing. It sometimes seems really high, but it's at least one yardstick available for brewers.
If you want a more cost effective route you could buy a packet of yeast and some yeast nutrient(or use a multivitamin), add them to 75-85*F water with molasses with the rough SG your brew will be at. Let it sit for a couple days, make sure to aerate. Then siphon off the spent wort and add fresh wort for a couple more days.
This will allow the yeast population to propagate and multiply two to three times.
Read up on the subject a little, what I stated is a very brief description and I didnt include many details.
Read this link, but you will be buying yeast so you can start at stage 2 or three propagation.Growing Yeast from a Plate - German brewing and more
BTW, you dont necessarily need flasks, beakers, stir plates, etc(though it probably works better)... I've done it successfully with just a mason jar, a pot, molasses, multivitamin, hydrometer, etc... just be sure to sanitize everything and work carefully. The yeast just needs nutrient, oxygen, and sugar to start reproducing.
