If you want to go on a tourist visa, make sure you have enough money to fund the trip, arrange the accommodation, and return flights. You must have a stable source of income and you'll have to provide a copy of 3 or 6 months bank statement. Once you feel you are ready, just apply for a visa.
You do not require an invitation letter.
If you have a close relative who is eager to fund your trip, request them for an invitation letter. You can't go around the internet asking strangers for an invitation letter.
