I assume you are planning to trek to EBC (Everest Base Camp).
I trekked to EBC in Feb/March 2017 with 11 friends , 2 guides and 6 porters.
Although most of us were very experienced self sufficient, self guided wilderness hikers we chose to use a trekking company for this one.
The price for the 15 day tour was about $USD1000. Currently similar tours seem to be $USD1200 to 1300. Incredible value.
I have just climbed out of my kayak after a long session so will keep this short for now.
A quick outline.
Arrived Kathmandu and transported to hotel by company.
Next day guided tour of Kathmandu temples and sights.
Planned flight to Lukla next morning but planes unable to fly due to weather a common occurrence. Transported back to hotel.
Next morning flew to Lukla, lunch at Lukla. The landing at Lukla is an experience. Trek to Phakding.
Trek to Namche Bazaar (unbelievable).
Next day acclim day around Namche did steep hiking, lunch in a little village. Back to Namche for the night.
Trek from Namche to Thangboche. Visited the famous monastery.
Trek to Dingboche. The views!!!
Next day acclim day Dingboche. Steep hiking, stunning!! Back to Ding for the night.

Trek to Gorak Shep. Drop off gear then trek to Base Camp. Back to Gorak Shep.
Optional up early to climb Kala Pathar.
Back to Gorak Shep then down we go. Slight change of track on the down stopping at Pheriche for the night.
Trek all the way through to Namche.
Trek through to Lukla stay Lukla for the night.
Morning flight from Lukla cancelled, all flights cancelled. Another night in Lukla.
Day if Holi, morning flight to Kathmandu. Company threw us a party, beer and nibbles. Company takes us out that night for celebration meal and drinks.
We stayed on in Kathmandu for a few more days.
Is that like what you are looking to do?
We used a company called Imperial Nepal Treks managed by Paras Khanal. I have had friends also use them. I would confidently recommend them.
It is possible to organise your own trek but honestly you would struggle to do it as cheaply and it might prove problematic.
Feel free to ask any specifics and I will try to help out.
