I don't you really want to have lots of awnsers. Instead, it would be way easier and efficient to get fewer quality awnsers from those you want to be attractive to.
I think for your pictures at first, you have to get it the way you want yourself to be appreciated during activities you would like to do with someone. Example, if you are someone calm who loves having some walks in the wood, get some great pictures of you naturally looking, in some outdoors spots, pictures your alone on it. Murphy's law always want your best friend to be looking cuter than you to the person your trying to gain interest from. Just one or two pictures with no sunglasses, no makeup, natural smile looking, and your on your way. You will get rid like that of thoses who disserve a hookup by not looking too sexy but more sweetheart and authentic instead.
For your text, be truthful and direct about what your exactly looking for. Kids, no kids, smoking or not, dirt, hyperactive or calm, pets... Short or long term plans you want to share with someone. If only one guy sees himself in what you are and what you are into, you'll have one great awnser :-)
Don't be superficial. IT IS IMPORTANT that both of you find at first each other physically attractive as you are right now. Don't try to take someone you will want to change for you one day. It will not. If you don't like mustaches, don't expect him to shave it for your beautiful eyes. You will end up spending month waiting to enjoy your candy as he will be sad knowing you don't love his mustache. Take someone who is like you want and like right now.
Love, peace, happiness, hugs and cuddles :-)
