If you haven't already go ahead and read the guides sticked on the forum its long but should be helpful. First of all I don't know how realistic you goal is for $10. $20 maybe but it wont be much the fertilizer alone will cost you about $5-$8, not to mention alot of the plants you will want will cost at least $2-$5 each. What substrate do you have now? Most gravels will work fine, a CO2 system can be DIY but you will still have to buy the yeast and sugar, look up DIY CO2 in the search on the forum. But in most cases CO2 is not necessary (again read the planted guide), and we also need to talk about your lighting, what is the bulb rated at? It should be at 6500k otherwise you will have issues with growth.
A little bit more research and money will go along way, even with $20 you would probably only be able to get a couple of sword plants and the root tabs they need, that's assuming you don't have to spend money on anything else.
Instead if you $10 is firm, you might look into some more beginner plants, such as Java Ferns and
Anubias plants, they should have ferts and the correct light but should survive with out it, even then it will only be a few but at least you can start somewhere and start budgeting for future additions.
