Hello we recently won a Business plan contest and we will start making our project ! our budjet is 1800$ for now to see there's no bot bid just start your pm with '' Hello, i'm humain " let me tell you about the project what i will do : provide hosting. buy domain names. ( you will tell me what should it be ) i'll developpe websites based on opencart , joomla , wordpress, and make a design for them. i'll make 5 niche blogs wich will be to advertise for some of our products so you must do to it : in each one you must write unique content ( 30 article 300 words ) of each blog so the total is 150 articles. ( let me know how much you do for this remember that our budjet is kind of low for those blogs, because it will be related to some store products, so you can rewrite some articles on internet and i'll provide subjects later. YOU MUST DO WHITEHAT SEO FOR THOSE BLOGS SO WE CAN LINK IT TO STORE AND HAVE SOME SELLS or WIN FROM ADS. ( 150$ max budjet for this ) what you should do for the store : To do some research on wich products people look for on internet. we will add around 10.000 product from anathor website to our store ( copy past ) budjet is 600$ and rewrite description of 250 words and make it seo articles around of 1000 product budjet is 150$ ( if you translate it to french you will get some bonus for sure ! 0.5$ per item ( only if u will do more then 30 ) then the description will be checked by the company who support us. Choice 50 keyword related to our products and do seo for our store to be in top google results. 900$ ( for 5 months ) ( if we get good results i will hire you again and again and again ... ) do some Ads on Adwords and facebook Too tell me how much time you need? what shall i tell you more ? and the budjet can be increased only if you send me bills from your company with a stamp and shipp it to me ( i'll use it as a proof to my supporter, so he can pay more, MAX BUDJET IS 2500$ ) I'm ready to hear your opinion too if you have a better plan so feel free to talk. Good luck.
