Sorry to be harsh, but you need to get a better artist. That tileset is terrible.
I suggest the following:
- Write out a . Be as detailed as possible.
- Buy a web domain and web host that can handle a game of this magnitude.
- Hire a professional or semi-professional game artist.
- Hire a professional or semi-professional web master.
- Hire a professional or semi-professional web designer.
- Hire a professional or semi-professional sound effects editor.
- Hire a professional or semi-professional musician.
Once you have all that done, shoot me a PM. If you pay me, I'll consider being your programmer.
Want a cheaper alternative? Learn to do this stuff yourself, and make your own game instead of asking others to make it for you for free.

It's very easy to pick up a book and start programming.
